First, I disagree with the time frames. Should be Pre-1950, 50s and 60s, 70s and 80s, 90s to present. At least the established 90s bands would knock out the crappy bands with only 2 albums in the past 10 years.
I'd have nominated Beyoncé even though she wouldn't have won because of the site demographics. That she wasn't even nominated speaks volumes. Muse should be in there IMO.
Portishead, Foo Fighters, Radiohead, Nirvana, Propaghandi, Stone Roses, Green Day, NIN, and more should all be in a 90s to present bracket.(or some of them not at all)
