The Sing soundtrack is revealing some odd pockets of music. The compilation, which dropped on Friday, features Reese Witherspoon and Nick Kroll, who both voice animated animals in the movie. Together, they cover Taylor Swift's "Shake It Off" with an electronic twist.

Illumination's Sing is about a koala (Matthew McConaughey) who launches a singing competition to save his failing theater. Witherspoon and Kroll play two very talented pigs who like to dance. Listen to their song below:

Other selections from the soundtrack include a duet with Scarlett Johansson and Beck Bennett, along with the previously released "Faith" with Ariana Grande and Stevie Wonder.
