I'm not sure how, but this brand-new joint mixtape by Soulja Boy and Young L somehow slipped past us last night. Perhaps it was the fact we were still sort of hung up on Soulja's newly revealed track with Game, "Too Faded," which actually didn't sound that bad. At all. Whatever the case, it looks like some of the tracks on Soulja and Young L's collabo tape, Mario & Domo Vs. The World, have been floating around for a minute. But it's always helpful to have all this material in one place, especially because we get the feeling that 2012 will be the year for Young L. You can stream the tape below and download it at Dat Piff.
