Given the contents of Barack Obama's iPod, it comes as no surprise that the Democratic presidential nominee has a pretty good knowledge of music. That knowledge was put on display last night at a town hall meeting in Powder Springs, Georgia, as Obama name-checked chart-topping rapper Lil Wayne in a speech discussing the importance of staying in school. Addressing the subject of dropping out of high school to pursue a hip-hop or basketball career, Obama said "You are probably not that good a rapper. Maybe you are the next Lil Wayne, but probably not, in which case you need to stay in school." The crowd responded with a standing ovation, as they could all agree that Tha Carter III is a classic. Obama also had a message for all the wanna-be Kobe Bryants out there, saying "I know you think you are, but you're not. You are over-rated in your own mind. You will not play in the NBA." There have been countless cases thus far of rappers name-checking Obama; this marks the first time Obama has returned the favor. Meanwhile, John McCain still thinks we should ban 2 Live Crew.
