My favorite mixtape by Wale is Mixtape About Nothing. You can download it for free on his myspace. As the title indicates, it is inspired by Seinfeld, a show that Wale says he has seen every episode of 30 times. Wale tackles big issues while peppering the mixtape with clever references and even an appearance by Julia Louis-Dreyfus. One of the stand-out tracks is "The Kramer," where he addresses Michael Richards racist tirade at the Laugh Factory.
Another personal favorite track is "The Perfect Plan" (noticing a pattern with the track titles? Seinfeld fans will). I even included this song on a mixtape I made for my students about the music industry.
