We all know Let It Go, and now Into the Unknown is quickly becoming the inescapable earworm of Frozen II.

With the movie being a musical and all, it obviously isn’t the only new song to have kids everywhere singing along.

The songwriters behind these ditties are Kristen Anderson-Lopez and Bobby Lopez, and the feature below presents a fairly in-depth interview with the talented pair. They tell the story of their involvement in the Frozen franchise, how they come up with their magic and a lot more.

Best of all, the pair perform songs from the new movie with simple piano and vocals.

Frozen II is now showing in Australian cinemas.
