Knock Knock- Mac Miller (Download)
Going to school in Pittsburgh may make me a little biased to Pittsburgh rappers like Wiz Khalifa but here is another. He's originally from Pittsburgh but now goes to college at WVU (which I wont hold against him).There is no doubt this song is pretty catchy and I'm going to have to keep an eye out for more songs from him.
