Mariah Carey's new album is starting life at the top.

"EMC2" has made its debut at the pinnacle of the national charts.

SoundScan reports the album sold 463,000 copies in the U.S. during its first week in stores.

And that makes it Carey's biggest sales week ever. Carey's last album made its debut at number one.
