Mark Serrano - Creator of MixtapeMonkey.com. MixtapeMonkey.com was launched on April 6th 2011. I have focused the last few months on pure dedication to this website. I almost failed my senior year of high school, ruined a relationship, and I moved to the other side of the country in hopes of making MixtapeMonkey.com an established free music download website. One day MixtapeMonkey.com will host the greatest Hip-Hop/R&B artists and play a part of the Hip-Hop culture. We got Hot Mixtapes For Yo Monkey Ass.
