Mariah Carey taps rappers French Montana, T.I. and pop/soul crooner Justin Bieber for an official remix of her latest single, "Infinity." Dubbed "Why You Mad," French and Tip add an enthralling street flair while Bieber brings a melodic smoothness to Carey's peaks.

Produced by Eric Hudson, the original version is lifted from the legendary singer's greatest hits compilation, #1 to Infinity.

Last Week, the famed vocalist teased a photo of her session at Hollywood Studios with Montana and Bieber working on the new song.
