I don't think most people understand that rappers for the most part is out of shape ass muthafuckas who smoke weed and drink all day... It's a lot easier going in the booth and recording your song in sections then it is to keep your wind through an entire song let alone an hour set while trying to not just stand there stationary on stage... I actually see this problem with singers even more! Cierra sucks live, she can only manage to hit her dubs cuz of all the fuckin dancing she trys to do at the same time..
