comparing: several trip-hop last.fm groups (to find bands + users)

Selam,

see below picture for a current comparison of several groups to find out (their) characteristic trip-hop bands/users

and here's a user whom I'll use to experiment more in finding good trip-hop music + users...
http://www.last.fm/user/more_trip_hop/journal

What do you think?
P.S.
- the analysis is NOT based on group connections (which the group leader decides), but: on unique group artists (which are influenced by group members)
- the image is automatically updating
- the table is cut + shows only the top artists
