Wiz Khalifa is a terrible rapper right?

He's given good beats and he does NOTHING with them. I like him, he's my 'guilty pleasure' music. But as a rapper, he is just...not good. all of the guest rappers on his tracks overpower him and are 10000% better then him. for instance, Big Sean in the song GangBang. His verse kills Khalifa's. Also, a large amount of khalifa's songs include long intervals of him going 'hahahaha' and 'uhhhh'...that's not rapping. and his flow sucks, & he only raps about money and hoes, and repeats everything. it just makes me angry to hear him given great beats, such as on the song Cabin Fever, and just ruin them. example - a href="http://www.youtube.com/watch?v=BM8tXxgNmIw" rel="nofollow"http://www.youtube.com/watch?v=BM8tXxgNm…/a
