For his new song with Busta Rhymes, it's more of the same. The new song, teased last week via Busta's Twitter, features a refrain instructing an unnamed entity to "calm down," but with rhymes like these, it's easy to do anything but.

"Calm Down" begins with a sample of Bob & Earl's "Harlem Shuffle," brought to prominence as the main horn blares at the beginning of House of Pain's "Jump Around." Here, the sample's right in the mix at almost all times, flanked by a drum machine.

The song's cover artwork depicts the two rappers locked in a comic book-esque battle, and that's sort of the feel represented throughout the entire song. "Calm Down" is like a battle rap between the duo, though Busta gets the brunt of the attention - it is his song, after all; Eminem's just along for the ride.

But at the halfway point of the six-minute tune, Shady takes over with his own brand of rapid rhyming, matching Busta's pace like it ain't no thing.
