YouTube’s copyright robots may’ve unwittingly launched the career of the next heavy metal superstar.

For the past three months, YouTube user GuitarHeroFailure has uploaded footage of his best Guitar Hero 3 performances to his channel—but when he tried to post his epic, head-banging run through Ozzy Osbourne’s song “Bark at the Moon” last week, he claims that YouTube removed it.

Instead of giving up there, GuitarHeroFailure decided to re-upload the exact same video with one key difference: He recorded original audio (comprised entirely of his own voice) so it wouldn’t violate YouTube’s copyright policy.

“This is a cool song, but it was taken down by YouTube,” he writes in the description, “so I fixed the audio.”

Fans of Osbourne’s original might be surprised by the less-than-faithful cover, which replaces the lyrics and guitar lines with scat-inspired “da-da-duh-da”s, “den-den-den”s, “shoobee-doobee”s, and a few “BWANG”s for dramatic effect—all delivered in a deadpan monotone:

For the sake of comparison, here’s Osbourne’s version:

For the sake of even more comparison, here’s a mash-up of the two, courtesy of Reddit user chopsu—and for yet another study in contrasts, here’s a more typical, scat-less video from GuitarHeroFailure’s channel, uploaded in November 2015:

After Reddit user samwitch645 shared a link to GuitarHeroFailure’s cover of “Bark at the Moon” with the Videos community, redditors discovered even more layers to the young gamer’s performance.

User GRONOlamp suggested rewatching the video with automatic closed captioning turned on, to see YouTube transcribe GuitarHeroFailure’s scat mumblings into pure poetry.

Here’s how the automated stenographer fared:

Some redditors hoped that GuitarHeroFailure’s viral a cappella jam merited a collaboration with Osbourne himself:

While others hoped the game’s creators would incorporate the song into a future release:

While Guitar Hero fans might not get an Easter egg, the official Guitar Hero Facebook page did share the video in a post—writing, “There is nothing on this Earth more metal.”

(And it’s only a matter of time before Ozzy Osbourne gives in and performs a cover of the scat cover of his own song.)

YouTube may’ve cursed and buried GuitarHeroFailure’s video (along with shame), and thought his timeless soul had gone in empty burning Hell with all the other copyright infringers—but it’s clear that he’s returned to prove them wrong.

So wrong.
