Guns N' Roses

The last.fm blog has a post on their efforts to clean up metadata, especially where there are areas of contention - asking, for instance, how many ways there are to spell "Guns N' Roses - Knockin' on heaven's door" (they have a list of the top 100 ways!). They also have a list of the various tags for band name on Guns N' Roses mp3s here: familiar reading for anyone who's ever downloaded music less-than-legally (I'm told), but worth reading down to the bottom of the list!
