I used to enjoy Spotify until their mobile app stopped letting me play specific songs from my playlists unless I got premium. I don't want their poorly sorted suggested songs, I want the songs I want. There's a ton of music on YouTube and SoundCloud, I wonder if it's within their TOS to index the url's of that and just have them play the videos using the supported iframe. Wouldn't block ads but it would on a browser with adblock.
