Chief Keef (aka Big Gucci Sosa) is at it again with another great hood-rat banger. While studying for finals, I can’t help but sing “I got a sack now” as loud as I can in the school library. Though I’m getting weird looks, I gotta hand it to Chief Keef for making another catchy song that gets me hyped, even at the worst of times. This kid has already had his music used in a Kanye West remix (Don’t Like), and he is only 17 years old. Gotta hand it to him. Bang Bang.
