It's been a long road leading up to the release of M.I.A.'s fourth studio album, "Matangi," which was originally supposed to come out in January. It has been such a long road, in fact, that M.I.A. once threatened to leak the album herself if it didn't secure a release date. That wasn't necessary, and now "Matangi" is officially out on Tuesday. To prepare fans, the Sri Lankan rapper uploaded the album's tracks to YouTube, meaning not another day has to go by before finding out what M.I.A.'s had up her "emo" sleeve all this time. #YALA.
