Did you have a good New Year’s Eve? Hah, of course you didn’t. But 2013 has begun, like it or not, and there’s plenty of content to consume now that everyone’s past all those stale jokes about the ensuing Mayan apocalypse. This is the life we’ve got, guys, and we’re going to have to get through it as best we can. Luke’s already on the beat, but there’s another fine song to score your mental commute back to the office: Azealia Banks’s “BBD,” an off-the-wall banger that mixes infinite polyrhythms against an expectedly sneering flow. Banks’s bottomless reservoir of confidence can get a little overwhelming at times, for those of us still not entirely over laying in bed and feeling bad about everything, but why not get the year off to a firm start? “BBD” stands for “bad bitches do it,” of course. Welcome to 2013.
