The music example is more acceptable though, because you don't pay a 1-time fee to own a song anymore.

When you "buy" a game, you pay a 1-time fee with the implicit calculation that you'll own that game for enough time for it to be worth the cost.

When you listen to a song on Spotify, there's no expectation that that song will be available next month, and it doesn't matter, since you didn't pay for the song.
