Lil Wayne is a moron. /hater
The two things that annoys the hell out of me about rap are:
1. The Singer - He kills the song 90% of time. He makes stupid moves and yelling YEH YEH YEH ever 2 minutes. I see no point into looking like an idiot. They're popular because they have bunch of cash, not because they're good. Although, there is a few exception.
2. Lyrics - They mean nothing. They're always the same kind, about hot girls,cash,drugs and gangsters. ''Come into my car yo man get raped by mah ***** yo ma gangsta, btw i **** your mom last night''
Again, there is a few exception.
The two rappers I have respect for are Eminem and 2Pac. Their songs have a meaning behind it, you can feel the emotion. They rap because they like it, not because they want fortune or to be famous. Plus their voices are not annoying.
There is surely alot of good rap songs, but it seems that people where I live don't know any of them
50 cent and G-Unit

I can list 20 artists that have meaning. It's Radio Rap you seem to not like.
