>>Outkast is hardly rock, I'd call it rap or hip-hop.
They really fit in hip-hop overall compared to rap lately.
But the song in question has no rap. It's really not inherently R&B. It's really just pop, and you'd really struggle to make a clear cut line between pop and rock in an electronic, synthesized type setting.
>>I think that Magnus has it right there in that the best songs would have to be the ones that really alter the definition of rock when they are released.
thanks

Of course the only problem with that is that if, for instance, rap/metal dominated and kept pushing "rock", then you'd have huge influences from things like RHCP and Les Claypool that weren't necessarily popular at all in comparison to most. Don't pick at the nit, just go with me. My badly crafted point is this: you can be tremendously influential without being popular, and vice versa, so you have to be all-inclusive. I really coulda said that shorter. Fuck it.
>>Nirvana,
some would argue Pearl Jam, but unsuccessfully.
>>the Beatles, Jimi Hendrix, the Who, Pink Floyd, etc.
Zep
>>Elvis was just a male Britney.
The bulk of his work's merit was made, even popularized, by others in some cases. Certainly Hound Dog isn't "his". But as the first superstar of the genre, nonetheless, you have to put him in there.
that's the biggest thing, though. It's very hard to put together a definitive list of top tens in anything of music without it clashing with a reader's own tastes.
