Starting with his guest appearance on Chris Brown's "Look at Me Now," Busta Rhymes has more often than not been flexing his double-time raps skills this year. And now he's apparently looking to capitalize on it (in a way) by releasing a track that is straight-up technical skills and nothing else. Seriously, dude's not really saying anything, at all, on "Why Stop Now," but his blistering delivery is still pretty intriguing, right? Sure, and it features Chris Brown, so the radio is going to latch onto this. Stream the track below and, if you're feeling gutsy, take part in the rapper's "Spit Like Busta Rhymes" contest on YouTube.
