The jokes in Pitch Perfect may have had us rolling in the aisles, but what really blew us away were the stellar cast's spot-on musical performances. This explosive soundtrack captures the most show-stopping numbers from Anna Kendrick, Rebel Wilson and the rest of the gang as they perform hits like the pop-reggae jam "The Sign" and the Madonna classic "Like a Virgin"—all entirely a cappella. Don't sleep on Kendrick's charming "Cups", a solo take on the Carter Family standard "When I'm Gone".
