I gave up on streaming music when I searched for the FFIX OST on Spotify and didn't get a result back.

I'm sure it works for most people, but half my shit is videogame soundtracks, 1/3 is hiphop mixtape, and the rest is a mix of Bandcamp albums and singles. I.e. none of that shit is on Spotify, Apple Music, etc. etc. etc.

I do use Songza for "mood-based playlists" though, since those are my favorite when I'm working.
