Listen: Mariah Carey’s Live Performance Of “All I Want For Christmas Is You,” Will Make Your Ears Bleed

Caution: What you are about to hear, you cannot unhear. Last night, Mariah Carey took the stage at the Rockefeller Center Christmas tree lighting ceremony in NYC, and sang her hit “All I Want For Christmas Is You.” Needless to say, she killed in…in the WORST WAY POSSIBLE. Like, she actually butchered the hell out of her own holiday classic. The Concourse released an unedited edition of the performance (above), which isolates Mariah’s vocals, and consequently made our ears bleed.

Mariah had it coming, though. The notorious diva was three hours late to the show’s taping on Tuesday night, and was asked to leave. NBC allegedly told Mariah that the only way she could perform at the ceremony is if she sang it live on Wednesday night. So she did…and then this trainwreck happened and crushed our Christmas spirit.
