Frozen 2: Fans CONVINCED new song Into the Unknown has huge connection to first film

When Frozen was released in 2013, it became an instant hit with Disney fans, children and families all around the world.

What’s more, Let it Go became one of the most singable and popular Disney songs of all time.

Belted out by Broadway musical star Idina Menzel, the powerful anthem resonated with listeners everywhere.

But while questions remained over the sequel’s soundtrack and if there could possibly be another song so successful, the latest tune seems to fill that spot.

And fans agree – Into the Unknown is the Let it Go of Frozen II.

In the latest trailer, a mystery voice guides Elsa (played by Idina Menzel): “Elsa the past is not what it seems, you must find the truth.

“Go to the enchanted lands and into the unknown.”

Off on their quest for another adventure and determined to discover what mystery power is draining Arendelle, Anna (Kristen Bell) begs her older sister to remain close.

“Promise me we do this together ok?” she asks, and Elsa assures Anna they will.

The sisters embark on their journey through the smoke as Elsa’s lyrics start pounding out: “Every day is a little harder, as I feel my power grow.

“Don’t you know there’s part of me that longs to go into the unknown. Into the unknown. Into the unknown.”

The clip ends with danger as Anna tells her sister: “I believe in you Elsa, more than anyone or anything.”

Taking to the comments, fans shared their predictions Into the Unknown would be the next major breakout track, like Let it Go.

“I guess ‘Into The Unknown’ might be Frozen 2’s ‘Let it Go’. It sounds good, I can’t wait to watch this<3,” one person guessed.

Another speculated: “This is the song, isn’t it. It’s the ‘Let it go’ of Frozen 2.”

“Let it go: Im the best most iconic song of Frozen ever. Into the unknown: Hold my drink,” a third joked.

While a fourth wondered: “So is this the song that everyone is gonna sing for the next two years? I’ll take it!”

“I feel like ‘Let It Go’ was a more pop-styled anthem, while ‘Into The Unknown’ is a powerful Broadway styled song and I’m LOVING it. So excited for this film,” a fifth shared.

Meanwhile, one person suggested: “I reckon the ‘let it go’ of frozen 2 will be a surprise till the release, but there are hidden clues(quotes) within the trailers, just like Frozen 1.”

Frozen II is released in cinemas November 22.
