Interesting.
Although Soulja Boy may not be mine (or many others) favorite, this is still a great mix for the amount of time spent on it. Great enough for me to actually listen through Crank That. I wish you'd done a little sound canceling on the Soulja Boy song to create some A Capella effect, for right now it just sounds like you placed two songs on top of each other. As you didn't actually create any sounds here, I can't really say much more! Cool mix, make some more but take a little more time, I'd love to hear.
