Listen to Mariah Carey's New Single, 'Infinity'

Singer drops first new release since her split from Nick Cannon.

"Why you mad / Talking bout you mad / Could it be / That you just lost the best you / Ever had / That's yo bag / Yep that's too bad," she sings in the new track "Infinity," from her upcoming greatest hits album, "Mariah Carey #1 to Infinity."

"Close the door / Lose the key / Leave my heart on the mat for me / I was yours / Eternally / There's an end to infinity / To infinity," Carey croons in the chorus.

Cannon confirmed last October that he and Carey, parents of 3-year-old twins, Moroccan and Monroe, were living apart.

Despite her personal turmoil, which includes a lawsuit filed in January by the former nanny to her twins, things are looking up for Carey professionally.

She recently announced a residency at Caesars Palace in Las Vegas.

The show, titled "Mariah Carey #1s," will open May 6, and then run in May and July.
