Ooof, getting called out in the OP. It's ok, I'll be your first reply.
This year marked the full transition to Spotify streaming for me. It's been incredibly relieving not having to constantly try and back up all my music and anxiously worry about losing it. In terms of my favourite music this year;
I don't know any of those artists xD
I too made the full transition to Spotify this year. I really badly miss not being able to rate inidividual tracks (out of 5 or 10, for example), and I get stuck in a bit of a rut sometimes of listening to the same 20 or so songs at the top of my liked list until Friday comes along with new releases. But like you say it's nice not to have to worry about organising and saving 100s of GBs worth of music and album covers.
