"Power pop" is a very flexible term. A lot of people here are miffed by the top artists, and, I think, for a good reason, too: they're hardly the most representative artists of power pop. It's pretty fucking weird and confusing, though. You don't see this kind of thing outside last.fm since "power pop" and "powerpop" are both synonymous with each other. Allmusic and RateYourMusic all have groups like Big Star and Cheap Trick under top artists/releases. All the power pop blogs I've read or skimmed through don't have anything to do with the bands or music here.
True, but I guess all the anger that floats around this page is how people feel that these bands are trying to "hijack" power pop and completely change its definition... much like how "R&B" meant one thing in the 1950s-1960s, and since the 1980s it means something else entirely.
NONE of these bands are power pop. Not one! Where are Big Star, Cheap Trick, Weezer, The Posies, Matthew Sweet, The Rasperries, The Quick, 20/20, The Cars, NRBQ, Nazz, Teenage Fanclub, or hell, even The Knack or The Who, since they came up with the name in the first place?
