Claiming "rabid" demand, Internet piracy and bootlegging, Eminem [ tickets ]'s label has moved the release date for the rapper's new album, "Encore," up four days to Nov. 12.

According to the label, the regular version of the album and a collector's edition, which features special packaging and a free ringtone, will be available on the new date.

"This is something we have been anticipating," label sales-and-marketing head Steve Berman said in a statement. "Once we had all of our pieces together we started a discussion as to whether 'Encore' should come early. We knew there would be a tremendous demand for this album. On our end, we were ready ... we just had to press the button on the date."

"Encore" is Eminem's fourth album. According to Aftermath/Interscope, the artist's previous albums have sold more than 50 million copies worldwide to date.
