I neither watch nor care about the Grammys anymore so I really don’t care who gets them.
These artists like to tell themselves that they are being rebels and that when middle America hears these words, we burst into fits of outrage. However, in terms of this being a statement about society, I think its more a statement of how banal popular culture has become. I’ve never minded swearing, sexual inuendo and other crude talk in music and literature but its very difficult to use appropriately. Almost all “artists” these days simply use it for sensational value, which is banal. Then they confuse the criticism of it with unreasonable Puritanical suppression of their “freedom of expression”.
If they REALLY want to be rebels, "expanding the envelope", they should try having a white band use the "n word" as much as the rappers do, or have any band make fun of Mohammad. Then step back.
