There are two main things you should you know about Njomza, Chicago's most precocious and outspoken R&B upstart. The first is that she makes incredible pop music; the second, that she just can't help taking her clothes off. Some advice: start by kicking back to the material on her latest mixtape, Gold Lion, a masterwork of chilled-out late-night slow jams, all graceful, auto-tuned perfection and sombre, Drake-like production. And only then look at its artwork.

Perplexed and a little irritated, I recently felt the need to facebook-comment on its characteristically visual photography. I commented, "Your music is lush but you really need to stop taking your clothes off." Her response? A simple "no." And so she went to receive many a like and I sat there in helpless, hapless humiliation. A guy called Terry even chipped in, "But how would she shower?" A fantastic point, Terry, thank you, but in any case, let's place this thorny substance-nudity disagreement aside for one second and appreciate the amazing music at stake. Below is the official video for the Mr Music-produced 'High', the lead single off the mixtape and a fantastic tune in its own right.

Moving on to someone a bit more established, following years of rumour and speculation, Norwegian blog-pop legend Annie finally returned last month with the unquestionably breathtaking 'Tube Stops and Lonely Hearts', her first single since 2009's criminally overlooked Don't Stop album. Produced by Richard X, the song is a return to form (not that she ever lost it), starring cyclic synth lines, wraithlike speak-singing and pulsing, clubby Madonna-isms. The video looks like it cost 2 or 3 krone but it still has effect. Annie, we are so glad to have you back.

From Annie to an Annie-influenced artiste, let me now introduce you to the marvellous FEMME, nom de plume of South East London-based, Goldsmiths-educated Laura Bettinson, whom you may recognise as the singer in Nigel Godrich's Ultraista project. As she puts it on her Facebook page, this new direction with FEMME is all about "Girls. Beats. Bass", but in reality she encompasses so much more. Most notably, new single (and free download) 'Daydreamer' is a bit like (*simile alert*) how Grimes would sound if she played around with traditional pop song structures and hooks and other things normal people actually like, whilst sticking with the whimsical, chopped 'n spliced vocals, catchy choruses and funny-sounding 4/4 presets. Just our cup of tea.

Last month's other big-name comeback was that of the mighty Kelis. And on the bold and staggering Dave Sitek-produced 'Call On Me', she shows she's certainly still got that trademark vocal thrust, but does something a little more retro with this time around, opting for a solid Motown backbone of horns, Hammond organ and disco guitar. Not much else to say about the overall package here, other than the fact that she's definitely conjured up a right banger, up there with the Eric Prydz number 1 of the same name, and that, yes, everything bodes well for the two (!) albums she's apparently due to release later this year.

'Habits', the new single from Swedish popstar Tove Lo, is one of the best pop nuggets of the year so far. Your typical break-up song about "the misery that comes with a broken love that you want to mend but you can't"; Lo's certainly not breaking new thematic ground here, nor new musical ground (think another, er, Annie-influenced Scandi-pop artist), she's just making amazing synth-pop anthems that make you want to jump up and down and do the shameless singing-into-hairbrush-in-front-of-mirror thing. Anyway, here's the official video. Warning: features creepy licking.

Finally, take a listen to this. Sinead Garnett first grabbed our attention with last year's guest-spot work on tunes by Rudimental ('Baby') and Disclosure ('Boiling'), but she's now set out on her own bassy, funky-influenced path. 'Got Me', her debut single (to be released soon), sees her team up with pro bros Eats Everything and Lukas, zooming up and down scales effortlessly with those highly versatile tones in a fun and carefree future club smash.
