Are they still "Loved" at last.fm?
as i mentioned in the release notes, you now need to have "synchronise loved tracks" enabled in the last.fm plugin settings
I don't use last.fm. Didn't even have an account. I just used that function to mark favorite tracks.
I have now created an account and activated the plugin with the enabled setting suggested by steven so hopefully the tracks will keep their "love" rating from now on.
Edit: Yeah, so that was not a good idea... Apparently it synced to my newly created account which didn't have any loved tracks and I've now lost the rating for about 1,300 tracks. Disabling the plugin again doesn't seem to bring them back. Suggestions or screwed?
