I've used spotify for a decade. But the other day I opened one of my playlists and noticed that almost all the songs were greyed out as "unavailable" despite a quick search showing those songs still existed.

Spotify rotted my playlists because it didn't feel like updating a database row somewhere when some licensing agreement got updated. Apple will do the opposite: Rot your music collection by replacing songs with "identical" songs that aren't at all.

So I'm thinking it's time to buy music again.
