I don't care really, all I know is that rap, along with jazz, certain classical artists and opera singers, and cuban/latin music are my faves. They just sound *right* to me, unlike rock and alternative and such. I like the way certain music flows, as opposed to rock music which just doesn't do a thing for me. I like the sound of certain rap artists' voices also, like Trick Daddy, Marques Houston, Three 6 Mafia, plus others. I wish I knew the exact reason that I enjoy the music I do, but meh, I'll figure it out eventually!
I absolutely can't stand Eminem and 50 cent, though. Refuse to listen to them. Eminem because he's a jerk and 50 cent, I just do not care for his voice or songs.
