You’re gonna have to buy this one to listen, friends. Go fire up the iTunes THIS SECOND to cop “Smash a Kangaroo” from Heaps Decent, the Australian non-profit offshoot of Diplo’s record label, Mad Decent. Maningrida kid raps, digiridoo samples and a whole lot of fun. All proceeds will help fund future Heaps Decent initiatives, so use your 99 cents for the forces of good instead of that Maroon 5 song we know is secretly in your shopping cart.
