one result was the characteristic jazz artists, see picture... as you can see this group does not fit in that sense with other jazz groups which must not be bad, it's something distinctive :-)
I've created now a last.fm user where I'll continue my experiments (e.g. by influencing with special amount of plays) ... to find other users ... http://www.last.fm/user/jazz_and_more/journal
if you know other jazz groups which could be included, please share, thx.
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) - only the image is automatically updating - the table is cut + shows only the top artists
