Mentally, I use handpicked spotify playlists as if it were an "indie" radio : They are curated (no Spotify algorithms), simple to "activate" (just play), and many are frequently updated.
One advantage is that I can easily "tag" certain music, to explore in depth, but also to find new playlists so that the cycle continues and the music never stops (like a radio).
Speaking of prog, I'm currently enjoying this 80+ hours playlist :) [1].
