Gambitowens is right in a way. that Hip Hop vs. rap shit is bogus. Rap music is a form of hip hop music therefore its hip hop, no matter if they rappin about bitches and ice, or cyphers and burners (the grafitti type). So yes, Gambit is right when he says rappers who make money keep hip hop afloat, but he is not right in saying that if it wasn't for these kind of rappers hip hop would die. Hip Hop will never die because the other art forms in it will continue to thrive regardless of rap music (and that's been happening for years). And who's to say that some underground emo, or underground fool on some "lyrical, metaphysical, -isical" shit is real hip hop?
The closest shit to real Hip Hop rap music is what all the old mufuckas was rappin about which was HIP HOPPIN at the block party... the only time these so-called MC's from the underground rap about Hip Hop music, most of the time now, is about how the mainstream is fuckin it up or how they are real Hip Hop.
Go listen to the Treacherous Three, the Furious Five or some shit, that's real Hip Hop rap because they rap about hip hop.
It's like before there was Rock music, and Rockers and all the sub-genres of Rock music, there was Rock N' Roll... and Rock n' Rollers talked about rock and rollin (the lifestyle and the music), etc.. Then Rock evolved out of Rock N' Roll, and it talks about all kinda shit and sounds all kinda ways (the only way to compare it to rock n' roll is that they play some variation of bass, guitar, and drums, and the rock artist before them that influenced them, and so on all the way back to Little Richard, Elvis, etc.).
