With all the BS thats currently on the radio, my opinion is that the rap/hip-hop genre is on its last breath.
"I got money
dont f**k wit me
im gangsta, n****
shake dat ass
ho gimme my money"
Sound familliar? thats 99% of mainstream rap.
For every one good rapper you can name, there are 5 more i can think of off the top of my head.
EDIT: If you have an ipod full of 50 cent and TI, I may insult your music, but dont take it personally.
