What of The Whit Stripes? Are they not popular in the U.K.?
I'd also include Outkast since their new album has taken their fame up a notch.
Evanescene? Natch. I don't hate them, but they don't bring anything new to the music world in my opinion.
Fifty's worth about 2 cent(s) at the moment. Bad move bringing G-unit out (or maybe it's good to exploit Fifty's popularity as much as possible now).
Johnny Cash, good choice.
Christina has enormous talent. But I don't think that it's being put to good use.
I don't think Dizzee Rascal has made it Stateside yet.
Oh, let me also include No Doubt. Because they just keep on chugging and their cover of Talk Talk's "It's my life" is on point.
P.S. I know this wasn't a "critique my choices thread" but I just couldn't help it. Sorry
