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

Hi,

see one result in the picture below

also: there's now this user:
http://www.last.fm/user/more_hip_hop/journal
I'll experiment more with this to find good hip hop bands + users
if you know other last.fm groups, please share, thx

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
