A culture and form of ground breaking music and self expression with elements that consisted of the elements of graffiti art, DJing, MCing, and breaking. Today Hip-Hop is considered to be dead in the mainstream because so-called mainstream Hip-Hop doesn't have the elements of hip-hop and have no meaning.
The stuff on MTV and the radio can't be called Hip-Hop because the lyrics don't have any meaning or self expression. Wack artists today just rap about their shopping lists and other bullshit. There are no more DJs making a prescence since artists today think they can manage without them. Without a DJ there are no scratches and cuts. No much graffiti art is being shown in videos. Artists such as 50 Cent, Nelly, Chingy, J-Kwon, P. Diddy, Cash Money Millionaries lack the 4 elements since their lyrics are ridiculous (no MCing skills), they don't have any DJ presence in their tracks (notice that so-called hip-hop today lacks scratches and cuts), and not much graffiti art is being expressed.
The point of this defintion is to show that MTV/Radio mainstream Bling Rappers should be categorized as Hip-Pop artists, not Hip-Hop artists.
