Demi Lovato's power ballad 'Let It Go' appears on the soundtrack to the animated film 'Frozen,' in multiplexes Nov. 27; so, it's no shock that the video meshes live action performance footage of the always-gorgeous singer with scenes from the film.

Lovato's hair -- which changes constantly -- is blonde and wavy here as she sings in an big house in which she is the only inhabitant, playing the piano and with a snow globe. The furniture is covered with sheets and it feels like its been abandoned. Lovato is the sole sign of life.

She is cloaked in black until the final minute, when she lets the light in, ripping the sheets off the scenery while dressed in a cream-colored gown.

Demi Lovato moves from darkness to light.
