Hot song: Childish Gambino's 'Heartbeat'

Even if Childish Gambino wasn't the rap identity of actor Donald Glover from "Community," there'd be a whole lot of talk about whether he was playing a character on his single "Heartbeat" (Glassnote). It sticks so close to Kanye West -- from rhymes to the flow to the Daft Punk-ish backdrop -- that you have to double check, but there are worse issues to have. Forget the questions and just dance.
