Well.. all really big forms of music seem to be despised by the generation that came before them.. just like rock was and just like jazz was before that.. so i guess all these people who dismiss rap as "just noise" are just following the trend that we've seen in all popular musical genres. I pretty much expect rap to recieve it's fair share of criticism until it is no longer the top musical genre in America.. it'd actually be sorta weird if it didn't.
