if i may, it seems that the few people who elaborated were 'complaining" that the songs all sounded the same (all one type/style of sound); not so much that it was new stuff, but that there wasn't enough "style" variety, for lack of a better term. not being an expert in this genre, i have no idea if there are enough new artists with relatively different sound styles or not, but that might be a place to start!?
of course, since i wasn't there i have no idea, and i may be reading too much into things, or putting words in others' mouths, but that's the impression i got...
