Yeeeah. Cash Money is -not- overrated. There shit stands the test of time, dang near 10 years since that stuff dropped. I was just listening to 400 degrees this morning. Manny Fresh's beats are crazy good, and when they came out, they were real original/futuristic. He also is a funny dude, and so when he gets on the mic or makes skits, its not all bad (bitin'-ass jazzy pha, take note)...
Most overrated rappers, in no order: (just my opinion)
3-6 Mafia (um, yeah, the beats are slappin, and I like some of the songs, but I just cant get down unless i'm too faded to understand what the lyrics are, cuz to me they're stupid. (and not stupid-good))
Eminem (he says some clever shit, and some songs are pretty nice, but only a handful of his tracks have any repeat value, to me he's a great guest appearance, thats it. I cant handle listening to two emimem songs in a row)
Ludacris (see eminem)
Game (I fail to see whats so great about this guy)
Tony Yayo (my friend dragged me to this concert and then was getting worried we were gonna get jumped or something cuz I was clowning him so hard when he was on stage, he even said in one of his lyrics that he's the 'best rapper alive'...Bwaaah, hah, hah, hah.)
