Up-and-coming New York rapper A$AP Rocky is a terrible singer -- which, surprisingly, is one of the many things that makes his sloppy, off-key and all-too-brief cover of 'Pumped Up Kicks' so damn fun. Rocky, who is gearing up for the September release of his debut album, 'LiveLoveA$AP,' recently laid down a cover of the massive Foster the People hit during a recording session at BBC Radio 1's Maida Vale studios in London for Zane Lowe's show.

Rocky's version is technically pretty terrible, but otherwise pretty awesome (and strangely addictive) in all the right ways. You can listen to his complete Zane Lowe show appearance here or skip straight to the good stuff and check out his 'Pumped Up Kicks' below, thanks to Fake Walls.
