Demi Lovato is returning to her Disney roots…

The 21-year-old part-Mexican American singer/actress and former Disney Channel star has released “Let It Go,” a single appearing on the soundtrack to Disney’s upcoming animated film Frozen.

“Let It Go,” which will be performed in the film by voice actress/Broadway vet Idina Menzel, gets a pop-rock makeover befitting of Lovato’s oeuvre, with guitar flourishes, orchestral punches and lyrics about triumphantly moving on.

“Up here in the cold thin air, I finally can breathe/I know I left a life behind, but I’m too relieved to grieve,” Lovato sings on the track.

The Frozen soundtrack will arrive in stores on November 25, right before the animated film is released on November 27.

Earlier this year, the X Factor judge contributed the track “Heart By Heart” to the soundtrack for The Mortal Instruments: City of Bones.

Lovato is also preparing to kick off her Neon Lights tour next February, with Fifth Harmony, Cher Lloyd and Little Mix as support.
