Spotify is arguably the most powerful music discovery platform on earth, but over time you will find your favorite songs arbitrarily disappearing from your playlists. If you stick with mainstream content, this is typically invisible. But, if you are on the edge following indie artists and experimental works, things are much more rough.
For me, taking favorited content out of people's playlists is unforgivable. Even if there is an unlimited amount of other acceptable content to enjoy. The feeling of loss is severe for me.
I've bought more physical CDs in the past 12 months than I ever have in my life. New content is still being stamped to plastic discs for those who are out of the loop. The new Dune soundtracks by Hans Zimmer (yes there are 2) being my most recent acquisitions.
