Get your holiday jam on with ‘All I Want for Christmas’ Carpool Karaoke mashup

Without a doubt, Carpool Karaoke is one of the best things on YouTube.

If you have never seen it, the idea is pretty simple: “The Late Late Show” host James Corden picks up a famous singer or band under the guise of helping him avoid traffic in the carpool lane and they all jam out.

Corden also interviews them during the rides and asks them about an upcoming album, their music or just life in general.

The episodes are always wildly entertaining and receive millions upon millions of views, but he may have just released his best one yet.

Corden invited Mariah Carey to cruise around town with him and, of course, they wind up singing her smash holiday hit “All I Want for Christmas.”

But it’s not just Carey and Corden. Apparently, without anyone knowing, he asked several big acts over the past year to join him in singing the song and added them all in, creating one heck of an awesome holiday mashup.

From Adele and the Red Hot Chili Peppers to Elton John and Lady Gaga, get ready for a rendition of “All I Want for Christmas” that you could only dream of putting on your Christmas list.
