Whoa, here's a nice surprise on this somewhat chilly Sunday afternoon. Azealia Banks might be in Japan right now, but that's not stopping her from sharing never-before-heard joints. This latest tune from the surging Harlem rapper is the boisterous "Fuck Up the Fun," which finds her spitting sharp, bravado-laced bars over a tribal Diplo production. No word on where this track will end up, though this is definitely way too ill to just be a freebie. Damn. You can stream and download the track below.
