Mariah Carey's "All I Want For Christmas Is You" is the #1 Christmas song, point-blank PERIOD. It's not up for debate. It's not a discussion. This is a holiday classic that we will show the aliens when they descend on us and ask us what Christmas sounds like.
Now, Mariah's place in the Christmas hall of fame has been secured yet again after "All I Want For Christmas Is You" surpasses 1 BILLION streams.
