You’ve heard it. Your kids have definitely heard it. Honestly, even if you’ve lived under a rock since 2013, you probably still know the chorus. It’s that massive, soaring power ballad that turned a Disney flick into a global phenomenon. But when people ask who sang frozen song let it go, the answer isn't just a single name. It’s actually a bit of a "choose your own adventure" situation depending on whether you’re talking about the movie, the radio, or the various international versions that took over the world.
The Powerhouse Behind Elsa: Idina Menzel
Most people are looking for Idina Menzel. She’s the Broadway legend who voiced Elsa, the Snow Queen of Arendelle. Before Frozen, Menzel was already royalty in the theater world, famous for originating the role of Elphaba in Wicked. If you listen closely to the high notes in "Let It Go," you can hear that specific Broadway "belt" that she’s famous for.
It wasn't an easy song to record. Songwriters Kristen Anderson-Lopez and Robert Lopez actually wrote it specifically for her vocal range, which is notoriously high and demanding. When Idina Menzel stepped into the booth, she wasn't just singing lyrics; she was acting out a massive character shift. Elsa goes from being terrified and repressed to literally building a castle out of ice. That’s a lot of emotional heavy lifting for one track.
Funny enough, the song actually changed the entire plot of the movie. Originally, Elsa was supposed to be a villain. Think more "classic Disney meanie" and less "misunderstood sister." But when the Lopezes played "Let It Go" for the production team, the directors realized the song was too sympathetic. You can't have a villain sing an anthem about self-empowerment and expect the audience to hate them. So, they rewrote the whole movie to fit the song Idina sang.
The Pop Radio Version: Demi Lovato
While Menzel’s version is what you hear in the film, Disney followed their classic playbook of releasing a "Pop Version" for radio play. That's where Demi Lovato comes in.
If you remember the music video with the mansion and the dramatic lighting, that was Demi. Their version is structured a bit differently—it’s shorter, more heavily produced, and skips some of the theatrical elements to make it fit into a 3-minute radio slot. Disney has a long history of doing this. They did it with "Beauty and the Beast" (Celine Dion and Peabo Bryson) and "Reflection" (Christina Aguilera).

Why two singers? Basically, movie songs are often too "theatrical" for Top 40 radio. Menzel's version includes character-specific moments, like Elsa throwing her crown or letting her hair down. Lovato's version is a standalone pop hit meant for a different audience. Some fans prefer the raw emotion of Menzel, while others like the polished, contemporary feel of Lovato. Both are valid, but they serve totally different purposes in the Frozen ecosystem.
The Global Phenomenon: 41 Different Languages
Here is where it gets really wild. Disney didn't just dub the dialogue; they translated the song into dozens of languages. There isn't just one person who sang frozen song let it go—there are dozens of "Elsas" worldwide.
In the Japanese version, Takako Matsu took the lead. In the Latin American Spanish version, it was Carmen Sarahí. These weren't just random singers; Disney looked for performers who could match Menzel’s specific vocal power and the character's personality. One of the coolest things Disney ever released was a "Multi-Language" version of the song where the vocals switch between 25 different languages in a single track. It’s seamless. You can hear the transition from French to German to Dutch without the melody ever tripping up.
The Oscars and the "Adele Dazeem" Moment
You can't talk about who sang this song without mentioning the 2014 Academy Awards. It was a massive night. "Let It Go" was nominated for Best Original Song (it won), and Idina Menzel was set to perform it live.
Then John Travolta walked out.

In one of the most famous blunders in award show history, Travolta introduced the singer as "the wickedly talented, one and only, Adele Dazeem." The internet absolutely melted down. For a few weeks, people weren't even searching for Idina Menzel; they were searching for Adele Dazeem. Menzel handled it with total grace, though. She later joked that she’s indebted to him because it made her name even more famous than if he’d actually gotten it right. The performance itself was a bit shaky—Menzel later admitted she was incredibly nervous—but it cemented the song's place in pop culture history.
Why "Let It Go" Hit So Hard
It’s not just about the singer. It’s about the resonance. The song became an anthem for dozens of different communities. People saw it as a metaphor for coming out, for dealing with mental health struggles, or for simply breaking free from societal expectations.
The Lopezes wrote the song in a single day while walking through Prospect Park in Brooklyn. They tried to get into the headspace of a girl who had been told to "conceal, don't feel" her entire life. That universal feeling of finally saying "enough is enough" is why the song stayed at the top of the charts for so long. It spent 33 weeks on the Billboard Hot 100. For a Disney show tune, that’s almost unheard of.
Technical Details: The Vocal Range
For the music nerds out there, "Let It Go" is a beast to sing. It’s written in the key of A-flat major. Menzel’s range on the track goes from an F3 to an E-flat 5.
If you aren't a singer, basically that means it starts quite low and ends incredibly high. Most amateur singers struggle with the "bridge" of the song—the "My power flurries through the air into the ground" part—because it requires a huge amount of breath control. Menzel’s ability to hit that final "The cold never bothered me anyway" note while maintain a conversational, almost defiant tone is why her version remains the gold standard.
