No Spotify
I installed last.fm on my android, and it scrobbled my pornhub history, that's unexpected and dangerous.
Why would I voluntarily use it to track myself and contribute to a commercial recommendation system?
Probably nostalgia, since I used last.fm service 10 years ago.
Later, I deleted my last.fm and spotify account.
Spotify forces users to sign up before listening, if I share a song from spotify, I'm encouraging and coercing people to sign up too.
Even 163music allow users to listen or preview without an account.
I'm not a fan of Richard Stallman, but he's right on internet music.
