Each year there are many, many, many, many tracks to sift through, get lost in, listen to, love, get addicted to, add to your commuting playlist, enjoy for just a week, enjoy for just a day, spot but forget to listen to until three months after it's out, mix, remix, share, play from your car, learn the chords to, or otherwise enjoy or like in some shape or to some degree.

So to celebrate the procession of tracks that have flown past us here at The 405 throughout 2015 we have selected a choice 25 of the best; in fact, not 25 of the best, but the 25 best tracks that we heard this year. We make our choices based on personal preference, of course, being irrational, feelings-led humans like everybody else, and what we back it up with - the production quality, the on-point sounds, the astounding vocals, etc. - may as well just be apocryphal.

2015 shattered towering music trends to rebuild a diverse sonic metropolis. The year has welcomed back the up-rise of consistent product-churning quantity and superior legacy-lasting quality music above all else, despite functioning throughout a hectic year of industry transitions. From the conversion of new music Tuesdays, to release date Fridays, a streaming revolution and a year-long Billboard rat-race that saw many breakout artists shatter chart records, it was the music fan that won. We got it all on a silver sonic platter. Wisdom straight from the creaky, throat-bolstered indie rock of Youth Lagoon, the manic operatic rock of Titus Andronicus and the smoldering and slow-burning synths, intertwined with Kelala's potent vocals that seeped into the pores of us.

Throughout the single-packed months, from spring to winter, we were gifted a fervent freelance-writer's battle cry from Rihanna, sparkly pop gold from Carly Rae Jepson and an introvert anthem from relatable loner poplet, Alessia Cara. Blessed by the veteran of digital sentiments, Björk's poignant strings stunned, Nao's silky voice stirred and Drake's controversial remix gif-fed itself until evolving into an unavoidable colour-blocked moment in music history. Bieber staged a comeback, Skepta led a universal grime takeover and Kanye West demanded the world's attention with raw audio from a live Brit Awards performance, where he debuted a banger amongst a sea of black hoodies and flames.

Genres blended. Artists took risks. Lyricism triumphed. Musicianship succeeded. And our list undoubtedly reflects that.
