In the same vein as my Wale recommendation, today I also want to talk about a mixtape. Everyone knows the name M.I.A. now because of "Paper Planes." Before a fully-pregnant M.I.A. swaggered at the Grammy's with Kanye and Lil Wayne, there was Piracy Funds Terrorism Volume 1. This mixtape by British rapper M.I.A. and American producer Diplo is one of my favorite CDs to listen to while driving.
On this mixtape, Diplo takes M.I.A.'s vocal tracks from her yet-to-be-released debut album Arular and mixes it with just about everything: The Bangles, Jay-Z, Ciara, Brazilian baile funk, reggaeton, etc... You can stream the whole thing on youtube or a quick internet search will help you find a place to download it.
