How would I access when a user (and a friend of a user) adds a song to a playlist, or stars a song in Spotify, Rdio etc?

You have to get the user_actions.music permission before you can read those.
The correct permissions is user_actions:music, not a dot.
- user_actions:music
- user_actions:video
- user_actions:news
http://graph.facebook.com/me/music.listens
http://graph.facebook.com/me/music.playlists
Those 2 endpoints still returns empty arrays.
