There was so much good music this year! Lots of exciting stuff from indie and major label artists, from "throwback-analogue-made-new" songs to "how-the-hell-did-they-make-that-sound?!?" songs. There were a bunch of great tracks that came directly from artists, and weren't available in the major music libraries (special mention to A$AP Rocky's "1 Train").
Most of the songs on this year's list come from albums that are also great, so if you like a song and haven't heard the whole album, I recommend checking it out.
