Mariah Carey isn't lending much credibility to Nick Cannon's denial of their rumored split with her newest, "You Don't Know What to Do" featuring Wale. There is no denying the meaning behind this track: Mariah (or her musical persona, at least) has gone through a break-up and now finds her previous beau aching to be hers again. Unfortunately for him, she's moved on, found herself and has no desire to rekindle their "little romance." As a result, he doesn't know what to do with himself. Mariah's dramatic intro on "You Don't Know What to Do" is appropriate, considering her diva status, but thankfully when the beat drops, we're presented with a much more upbeat song well-fitted for getting over an ex and making sure he knows it.
