This morning when we arrived in the MTV Newsroom, we were alerted to the most important holiday-related news of the year: Justin Bieber and Mariah Carey‘s duet of “All I Want For Christmas Is You” leaked online.

Listening to the hotly anticipated track, we were struck by … well, by the fact that Mariah’s vocal seems identical to that of her classic original. It’s the same vocal, right? It’s not just us? We’re not hearing things?

Mariah’s original “All I Want For Christmas” is our favorite Christmas song. Having listened to the song approximately 12 million times, we feel confident that we’re right.

But you tell us. Above is Mariah’s original and after the jump is her duet with Bieber. Listen closely then vote in our poll below.
