Rapper's Delight (With Christina/Britney Side Note)

Now don't get me wrong, I am the occassional fan of rap music. In fact, some of it is great, but a lot of it is in actuality terrible music. Most of beats to the songs are ripped off from some place. It also happens to be probably the most egocentric form of music.
I saw the VCast commercial with "Fergalicious" the other day and it made me think how rap is the only form of music where someone can get away with making the chorus to the song their own name. No other brand of music would let you get away with that. Like, you'd never hear John Mayer record a song called "I'm John Mayer ... J-O-H-N John Mayer ... all the girls on the planet are digging me ... I'm so sexy and so handsome and there's plenty to see ... I'm J-O-H-N John Mayer." Wouldn't happen.

Sidenote

I've always been in love with Christina Aguilera, but, hey, did you ever think you'd see the day when Christina Aguilera was much prettier, sexier AND cleaner-looking than Britney Spears? Me neither. Britney won the battle, Christina won the war. Who woulda thunk?
