Let's just get this out of the way: Yung Joc's new "Coffee Shop" is perhaps the single most socially irresponsible track we've heard in a minute: an impossibly catchy, children's show-ready song about slanging rocks ("Kids, don't do drugs. Bring 'em to me!" isn't much of an advisory warning). But in terms of jams? We didn't say impossibly catchy for nothing. Joc gets his sing-song Backyardigans flow on, Bad Boy South headmaster Block speeds his voice up like a thug munchkin, and we can only imagine how insane the video for this is going to look. "Welcome to Starblocks"...
