You've heard the preview before -- but now the full version of the "Glee" cast singing a mashup of Michael Jackson and the Yeah Yeah Yeahs for the show's Super Bowl episode is here ... and it's awesome!

The first listen below comes courtesy of PopEater, and the slick track mixing "Thriller" and "Heads Will Roll" definitely doesn't disappoint.

A couple other songs were released over at, including The Warblers singing "Bills, Bills, Bills" and Lea Michele and Mark Salling tackling Lady Antebellum's "Need You Now."

Check out the song below -- plus sneak peek pics from the Super Bowl and Valentine's Day episodes in the gallery above!
