If there’s one thing we learned from Disney’s 2013 animated film Frozen, it’s that we just can’t let go of “Let It Go.”

The epically catchy tune, belted out by Idina Menzel in true Broadway-powerhouse form, inspired an entire generation of ice-queen wannabes and probably echoed through your head for at least a few years (if it ever stopped).

It also generated a slew of creative covers, parodies, and remixes. With the upcoming release of Frozen 2 later this month, it’s no surprise that some of these rousing renditions are once again gaining traction across the internet.

Nerdist reports that the Klingon-language version of “Let It Go” was recently mentioned on Reddit’s Star Trek thread, much to the delight of musically inclined Trekkies and people who just love a good fandom crossover event.

Though some commenters quickly pointed out that, among other things, Klingons do not like the cold or letting things go, the overall opinion was that the song was not only well-executed, but also eerily enjoyable.

The track, whose Klingon title is “yIbuSQo,” was released five years ago by a SoundCloud user named Jen Usellis, or “Klingon Pop Warrior.” The somewhat dulcet tones of an acoustic guitar are offset by the guttural sounds that characterize the Klingon language, giving this version a strangely aggressive edge. Elsa’s original number was never really a lullaby, though.

If the moniker “Klingon Pop Warrior” made you think that maybe “ylbuSQo” isn’t the only song Usellis has sung in Klingon, you would be correct—also available to stream on her SoundCloud channel are Pat Benatar’s “Love Is a Battlefield,” Lady Gaga’s “Bad Romance,” and Celine Dion’s Academy- and Grammy-winning ballad “My Heart Will Go On” from 1997’s Titanic.
