Mariah Carey's 1994 holiday hit 'All I Want for Christmas Is You' has quickly established itself as a neo-standard. Now, it's being reworked and reimagined by pop music's most viable and smooth crooner, the infinitely charming and always stylish Michael Buble!

The song will appear on the singer's new album 'Christmas,' due out Oct. 24. MB's version of Carey's classic is so markedly different from her upbeat version that it almost sounds like an entirely different tune. Sure, the underlying melody is familiar and easily recognizable, but once Bublé opens his mouth and laces the song with his signature vocal flair, it's a whole new game. Not to mention a whole new song.

Carey and Buble both have huge voices and it's interesting to see how they attack the same song in totally opposite ways. The song bends according to Buble's stylistic changes and never suffers under the weight of the makeover; in fact, it's enhanced! The song's structure truly is flexible.

Buble's modern Rat Packer style fits the song perfectly. Whereas Carey's version was jingly and jangly, and almost cheerleader-like, Buble's is a slower, much more romantic and utterly dreamy! He slams on the brakes and pulls back from the bright bells that adorned Carey's original and croons warmly over the melody.

Who knew a song full of holiday cheer could make one swoon or weak in the knees!

Curl up with some peppermint-spiked hot cocoa and your loved one, and turn this baby up.
