Last.fm doesn't allow "untitled", "various artists", "track 01" and other titles that may suggest the song is incorrectly tagged. This leads, of course, to edge cases where an artist has a track named "untitled" and it can't be scrobbled.

Moreover, last.fm also has an issue with unicode characters and some artists/albums may have two or more different profiles. It's a mess!

I actually was more traumatized when I discovered that artists with the same name are filed under the same ‘profile’, and just have a textual explanation that they are actually different. You'd think that a service purporting to do ‘big data’ processing could grab discographies off Discogs or something, and compare the album titles.

Anyway, personally I long since abandoned Last.fm in favor of more hands-on discovery.
