As reptile said, Lists suck! Its just someone's opinions, and even going on record sales, you still can't compare, because how can you "translate" them into now a days, the music industry today is fucked.
Secondly, *GROAN* can people PLEASE get OVER Nirvana. Great band yes, but seriously making Kurt Cobain into some Lennon like God or epic proportions is silly. Just because he was stupid enough to kill himself, doesn't mean that we have to wail with saddness over a "loss" to the world. I bet if he was alive, Nirvana would have run its course, and end up in the same place as other "indie" bands. I think him dying increased the bands popularity and gave it that special something (COUGH TUPAC COUGH) that neccessarily wasn't there. AND if he hadn't have died, we possibly wouldn't have had the Foo Fighters and for that i would have been very sad. hahah
To me, I adore the Beatles because they had such a variety, they're lyrics were poigniant and beautiful, they made great songs together and solo, and they (as lots of people have said) were totally orginal. Nothing sounded like them.
Also i think thats why I love U2, for the exact same reasons. I'm a lyric/melody girl! weeee!
