Never ever, EVER confuse greatness with popularity. Compared to music here in the U.S. British music is as good as it gets. It's true that bands like Pulp, Suede, Blur, Oasis, Manic Street Preachers, rarely get any airplay here in the states, but that's all I listen too.
In summation, if you really think "butt-rock" bands like Limp Bizkit, Creed, and Nickelback represent some kind of golden age for rock music here in the states then this is a very sad state of affairs indeed. We're a long way, away from Motwon, The Sounds of Philadelphia, the great punk rock bands of the the 60's and 70's (Stooges, Ramones, velvets), and the original alt rock of the 80's (Husker Du, Talking Heads). As far as I'm concerned British music is where it's at. And I'll leave you alone with your Kid Rock thank you very much!
