Last.fm was ruined by, I think, CBS.

Their recommendations were miles ahead of anything Spotify, Apple or Google have ever managed. So last.fm killed off the radio, the streaming, then started playing random Youtube vids for each track - very often a poor rendition, or a cover etc.

I gave up years ago, but still miss that recommendation engine that drove the radio stations - I discovered so many brilliant new-to-me artists through that. Scrobbling listens into a different platform or recommendation engine is the least useful part of what they did.

I'm actually surprised the site's still there!
