Yes, I've been scrobbling using audioscrobbler/last.fm since 2004 and this is quite bad for the experience. I've been listening quite a lot to a german dnb act called Panacea ( http://www.last.fm/music/Panacea ) the latest month. In my listening stats a picture of an american base hip-hop group shows up. Take a look at how Discogs (one of the best services I know) separates their artists with similar names ( http://www.discogs.com/artist/Panacea , http://www.discogs.com/artist/Panacea+%282%29 ).
