So apparently there's this young British dude by the name of Ed Sheeran -- that's him in the above picture -- that blends hip-hop, soul, and folk in his music. And even though he's 20, he's been touring his ass off for several years and has dropped a slew of EPs. Last September, he released his full-length debut, +, which earned him a number one spot on the Billboard U.K. Albums chart. Not too bad, and neither is this new track, "You Don't Know (For Fuck's Sake)," with unlikely collaborator Yelawolf. While we're not terribly keen on hearing Yela spit on more tunes like this, he does kind of kill it. Right? Stream the track below.
