It still has comments on albums/songs/artists, but most of the conversations are a bit dead.

I've still been using it since it's the best service (in my opinion) for simply tracking everything you listen to. Spotify does track the same thing but they don't really let you view the information the same way. For example, there's no way to view the list of your top artists ever like there is with last.fm (I just checked mine, it's: https://www.last.fm/user/[your username]/library/artists).

Hopefully the developers being unchained from CBS/Paramount can only mean good changes are coming to last.fm in the near future.

You can install your spotify and pull in all the data from Spotify.
