"I proper love IceJJfish," a then 24 year-old Jacob 'Raleigh Ritchie' Anderson declares as we share a pack of Haribo sweets (he's turned 25 as this interview's gone live). "D'you know him?" he questions. I don't. "Or Lil B? And ILOVEMAKONNEN; he's not the best singer, even by chart standards, he's not the best songwriter. But he's doing his thing. I respect that! Same with Lil B, I think he's putting his heart into his music. Or maybe he's not actually. Maybe he's just sitting there for five minutes writing a song. [Laughs]"

Bristol-born Jacob Anderson is more than just your typical entertainer. In fact, he's so far away from being a "celebrity" that you'd probably just walk straight past him on the street, despite having all the makings of a superstar. He's a bit of an unnecessary worrier, and has elements of a big kid (minus the immaturity), yet when combined, it strangely works in his favour.

He moved to London as a teenager when the acting work picked up steam, but things soon turned sour and he ended up in what he describes as a "dark place" before seeking therapy (which he didn't enjoy). He's a lover of cartoons (later reels off a list of shows that he's currently watching) and he's incredibly knowledgeable when it comes to music; be it his own or someone else's. Jacob rather famously appears in HBO fantasy drama Game of Thrones, however, his acting credits stem further back to Brit-flicks such as Adulthood, Demons Never Die,, and he's also appeared in a number of British TV shows such as cult cop classic The Bill, Broadchurch, Spooks, long running hospital drama Casualty and Silent Witness. But on this occasion, I'm reluctant to touch on the acting side of things. How many times can he talk about winning the role of Grey Worm and still keep it interesting? I'm confident he's been asked which job he prefers a thousand times over the past few weeks alone and quite frankly, on this occasion it doesn't matter. History has taught us that it's ok for actors to become singers and vice versa.

Shortly after his appearance in Broadchurch back in 2013, Anderson announced that he had signed a record deal with Columbia Records, which probably came as a surprise to many, including myself. But as he'll tell you himself, he'd been writing and singing for many years before the acting gigs came along. He mentions that the Raleigh Ritchie moniker is more of a "band name" than a full on name change or an alter ego, there's no difference between the two and in the acting world, Jacob Anderson still exists ("But I'm the band. A one man band!"). He's been writing for as long as he's been acting, so going into the music game he already had a vague idea of the musician that he wanted to be. "There's a couple of songs on the album, actually, that I wrote and recorded before I was signed. I definitely had an idea of the kind of music I wanted to make at least. But even now I don't want to say... I'm "this" thing. I'm really conscious and weary of saying I'm one "thing" because I know in say... six months time, which is when I'll probably start the next album, my head will be in a different place and I might end up writing something that's the polar opposite of what the first album is."

Typically, at least once a day you'll find something called The Daily Raleigh on his Twitter page. It's a playlist of his favourite tracks, which he describes as the "weirdest thing ever" because of its inconsistency. But in its inconsistency lies the beauty of what makes him, and his sound, so unique. His inspirations stem far and wide, from Tom Tom Club to Regina Spektor; M.I.A to Pusha T. "I have a really weird way of listening to music." Two days are never the same and as a direct result, his playlist has turned into the ultimate '90s kid mixtape. "It's really non-specific. I listened to it the other day and it's the weirdest playlist because it's so inconsistent and that's the nature of how I listen to things. I'll listen to things in chunks."

Judging by his releases so far, the theme of "expect the unexpected" already runs deep in his musical output. Most listeners probably expected Ritchie to become synonymous with releasing songs identical to 'Stronger Than Ever', with big thumping choruses filled to the brim with emotion. So far he has defied the odds and gone with a range of singles; each sounding rather different to the last, such as the heartfelt 'Free Fall', the funk-filled 'Cuckoo' and recent single 'The Greatest' which shows a more playful and entertaining side.

He confesses that he's scrapped his debut album a few times (assuring "scrapped" is a rather extreme word) and at the time of us meeting, there's around a month or so to go until he has to hand in the final draft to the label. As a self-confessed perfectionist, he wants his debut to really be the best it can be but he's also aware of the difference between making and releasing an album over making and releasing an EP. "With the first EPs they said 'Do what you want, put out what you want and let's see what happens.' Whereas an album takes for 1. It costs a lot more to put out and for 2. And this is something that's taking a while to understand fully, you've got to do the singles thing. You've got to put together a campaign otherwise no one's going to buy the album. But creatively, it hasn't been a problem luckily, I could have signed to other labels where creatively they could have been a bit more dictatorial." He claims that Columbia have given him free reign over what he wants to do but knows that at some point he's still going to have to listen to what they tell him when it comes to putting single-worthy material into the ether, admitting that he can be a little "bratty" when he doesn't get to upload all his music at once. "There's kind of a bureaucracy to the music industry that you have to follow; that everyone has to follow. It'd be great to say 'Oh, I want to put this out whenever I want!' but there's no point in doing that if no one is going to hear it."

We're meeting on location at a rather bizarre studio in Hackney, East London where he's filming his session for Vevo DSCVR, performing EP cut 'Bloodsport.' It's full of nick-nacks, bric-a-brac and other randomly acquired items; plastic see-saws mirrors, wicker seats, mirrors - it's all here and Raleigh's particularly fond of the rocking horse in-between takes. Off stage and out of performance mode, he's rather quiet and subdued, happily chatting away with his band, but once the switch is flipped, he transforms into this unexpected ball of energy, bouncing around the limited space he has. The cameras are frantically trying to keep up with his movements; it's rather entertaining. You think that he's going to go left and he goes right, it's almost like he's knowingly doing it at times. But when you step back at look at the amount of energy, the amount of soul and heart and emotion that goes into his performance, he's very clearly just lost in the moment. It almost looks like an out of body experience.

Once rested, we finally have a chance to sit in two random seats in the corner of the room. Despite the long day, he's still chirpy and energetic and even enthusiastic about having to sit with journalists. We randomly touch on the topic of songwriting, which he says isn't a difficult job when you're not looking for a hit (going in with the intention of writing a "hit" is the wrong mentality he says).

His single 'Stronger Than Ever' became something of a sleeper hit for him after it appeared in commercials promoting the launch of broadcaster ITV's new channel 'ITV Encore'. The track began to rise up the charts again, prompting a rush re-release which in turn prompted a cover by Lily Allen in BBC Radio 1's Live Lounge. "It kind of threw everything off a little bit," he confesses "because that song came out in January and then it was re-released in June." However he strongly believes there's no secret formula to writing a song. "I think people underestimate themselves. I feel like I've read a lot of things with artists talking about difficult it is and I literally just said a few minutes ago it's difficult to write a song so I get part of it. But also, I feel like some people overthink it; all it is, is describing how you feel about something; anyone can do that. It doesn't have to rhyme, it doesn't have to be a certain length, it doesn't have to be anything. Songs don't have to be anything. But if you want it to chart or want it to be on radio then maybe it does. You need rhythm and you need to be able to... no, you don't need to be able to sing in tune, as long as you sound like you mean it. [Laughs]"

'Bloodsport' originally appeared on his Black & Blue EP back in 2013 and is considered a firm fan favourite. But as Raleigh pointed out, it's never really had a moment to shine on its own. "I think it was originally going to be the first single from the album but I kind of wanted something new to be the first single so we went with 'The Greatest'. It's never been a single and to be brutally honest, of all of my songs, it's the song that people tweet me about the most and it's had the best response of anything I've put out." He mentions to me that there are slight difference between the version found on the Black & Blue EP and the version that he's performing today, one being the addition of a real strings section after working with Rosie Danvers, who has previously worked with Kanye West and helped provided the strings to 'Stronger Than Ever'. "She's incredible; she's my hero. Once we decided it was going to be on the album, I said "Cool, let's put strings on it!" That's something I always wanted to do. There's fake strings on the Black & Blue version and I hate fake strings. I really don't get on well with them."

There's further changes he's made to it, things that he felt he "could have done better" when it was first recorded. But the bigger question is, what does the album sound like now? "The album that I'm going to put out, which I know what that is now, is not the same album as the album that I was working on a year ago." He points out that he has enough material for "about four or five albums" and admittedly is still working on a final tracklisting. "I'm still doing it now. I know what it's going to be but things can still change and I'm still writing at the moment and in fact, there's a song that I finished the other day that's probably going to be on the album! [Laughs]" He's aware that people have been waiting to hear a full length project from him. He has an active fan base who seemingly document almost everything he does. He's not comfortable with the term "fans" however, instead opting to call them his friends. "I find it weird calling people 'fans.' Can you have fans before an album?" I assure him that you most certainly can before asking if he gets regularly spotted on the street (The Evening Standard ran a piece that claimed someone shouted "F*** yeah, Grey Worm!" to him on a New York subway). "No one's ever really weird with me. People just tend to be really nice; they say hello, sometimes they want a picture. I've never had any bad experiences!"

As the studio begins to quiet down and we wrap things up, I ask if he's ever wondered what he'd like his musical legacy to be. We jokingly talk about Kanye's recent attempts to walk on water while performing in Armenia and wonder what legacy he would leave behind. I say his legacy will be disruption but in a good way, while he believes he should be remembered for taking risks. For Ritchie, he would be happy to just have a legacy and to just be understood. "I guess I just want people to feel what they got out of listening to my songs made them feel better about something in some way, even if it's a small thing. All of my favourite artists are artists that I feel understand me and I know they're not thinking about me when they writing those songs but I hope that in some way. At least part of the legacy I want to leave is that people feel that way about me; people feel that I understood them or they understand me."
