Was happy for a time, then I realized I only listen to the same playlists (generated playlists don't work for me as I need some time to appreciate new music). Now I use YouTube/SoundCloud to check out artists' releases, and then get the whole album if it's interesting.

I have a decently sized library with my favorite albums and that's been sufficient for some time now. Every once in a while, I track new releases and explore new genres, then add the few that picked my interest to my library.

Intentionally is great for enjoying art (and YouTube is more than enough for mood music)
