I'll never understand Spotify. If it's such a pain in the ass why do people use it? Napster was big when I was in high school so if I find a song I like, I go download it. Sometimes it's piracy. Sometimes it's a legitimate purchase. Whichever is easiest.
Done. The end. It's mine forever.
As far as discoverability goes it helps that there have been no new music releases in the past couple of decades that I care about.
