Obviously Eminem has more on his mind than "butt squeezing season," Michael Jackson and making everyone report to the dance floor. "Mosh," another track from his upcoming Encore LP, has just surfaced and finds Slim Shady lyrically indicting the president while pleading with his fellow Americans to unify in insurgence and be heard.

"They tell us 'no,' we say 'yeah,' " he raps on the Dr. Dre-produced track. "They tell us 'stop,' we say 'go'/ Rebel with a rebel yell, raise hell, we gonna let him know/ Stomp, push, shove, mush, f--- Bush!/ Until they bring our troops home/ Come on."

Later on in the song, Slim Shady talks about having mosh pits outside the Oval Office, calls Bush the real weapon of mass destruction, and volunteers to be the voice of the people.

"Maybe we can reach al Qaeda through my speech," he adds. "Let the president answer on higher anarchy/ Strap him with an AK-47, let him go fight his own war/ Let him impress daddy that way/ ... No more blood for oil."

This isn't the first time Eminem has chosen to politically galvanize his fans or rapped about the commander in chief. In May he was the keynote speaker at the Detroit Hip-Hop Summit, which was heavily geared toward voter registration (see "Eminem Rallies Hip-Hop Fans To Vote, Hopes to Regain His Own Voting Status"), and in December a record called "We as Americans" was leaked on the Internet and in the streets.

The lines "F-- money/ I don't rap for dead presidents/ I'd rather see the president dead/ It's never been said, but I set precedents" were heard from the 'hood all the way to government offices and caused the Secret Service to investigate. After looking into the matter, the agency dropped its probe of the rapper (see "Eminem No Threat To President, Secret Service Declares").

"Mosh" and the rest of Em's Encore set is due November 16 ("New Eminem Album, Encore, Due In November"). The track is already floating around online, though, and is on the latest mixtape from Eminem's DJ, Green Lantern, Shade 45: Sirius Bizness.
