Is Mariah Carey's Improvised Holiday Jam Her New 'All I Want For Christmas Is You'?

Mariah "Queen Of Christmas" Carey is here to lock down her throne.

Though Mariah Carey's musical prerequisite to having a happy holiday season, "All I Want For Christmas Is You," was recently dethroned as the most-played holiday song in retail stores, there's no denying its dominance as the top track of the season.

And if there's ever to be another tune that reaches the highest heights that one did, it no doubt has to come from Mariah herself. Perhaps it already has.

At a concert at New York's Beacon Theater this past Thursday, Mariah got loose, improvising a new, off-the-cuff Christmas song with her piano player called, fittingly, "It’s Christmas In New York." A fan-made video captured the entire thing:

"We make up Christmas songs when we're in a happy, jolly mood," Mariah says to start things off before rolling into a lilting, twinkly, snowy tune complete with snaps and sparkly chimes.

"I'm freestyling, and it's not my best," she admitted near the end, "I feel like a dork 'cause I don't know much to say about it." But to my ears, it still sounded like the audio accompaniment to standing in front of a Bloomingdale's window display in December and seeing the red, green and white decor in all its glitzy glory. Or at least a movie-scene approximation of that kind of event.

All hail the Christmas Queen.
