As expected, Frozen 2 [1] brought fans exciting twists and turns [2] and an undeniably catchy soundtrack [3] that we'll be rocking out to well into the new year. On Dec. 5, Disney released the full video of the record-breaking sequel's [4] most defining song, "Into the Unknown," and we're getting chills just listening to Idina Menzel [5] belt out those high notes!

Written by Oscar winners Kristen Anderson-Lopez and Robert Lopez, the musical scene shows Queen Elsa as she ruminates on her desires to venture into, well, the unknown! Elsa — who was always a bit repressed with hiding her powers in the first film and taking on the crown under a lot of stress — sings along with a mysterious voice about feeling like there must be something more for her outside Arendelle. We won't spoil the movie, but let's just say that Elsa definitely gets a taste of the unknown [6] after this musical sequence! Watch the video above.
