"It's Always Sunny In Philadelphia" fans are undoubtedly familiar with the Dayman, a hero born from the deranged, spray-paint clouded mind of one Charlie Kelly. Legend has it that the Dayman (who may or may not be Kelly himself) developed some strange and remarkable powers, as a result of a strange (and very problematic) encounter with the Nightman, his archnemesis. One day, Kelly decided to turn the story into a song; Together with his drinking buddy Dennis Reynolds, the two formed a band called Electric Dream Machine and took the legend to the big stage.

The audience at Paddy's Pub came away from the performance relatively unmoved – there was a fair bit of heckling, due in no small part to the duo's ridiculous outfits – but YouTuber and "Always Sunny" fan Brian Nichols walked away with knowledge of "Dayman"'s true power: with its good-versus-evil storyline and über-dramatic arrangement, the song's as cvlt as it gets. Naturally, then, he's adapted Electric Dream Machine's classic into a Trivium-esque banger. Check out the "Dayman" metal cover below. Charlie would be proud.

Here's the original performance, in all its glory:

Chicago-based guitarist Rob Scallon is known for innovative renditions of metal songs, such as covering Cannibal Corpse and Slayer with banjos and ukuleles. The musician is mixing up his annual "May-Tallica" YouTube series, in which he traditionally shares creative versions of Metallica tunes throughout the month of May, by including offerings from System of MAY Down, MAY-Shuggah and Iron MAYden. So far, we've seen Metallica's "For Whom the Bell Tolls" played entirely on bells, System of a Down's "B.Y.O.B." being performed on a cello at a romantic restaurant and Meshuggah's "New Millennium Cyanide Christ" on shovels.

In Scallon's latest installment for the month of May, he performs riffs from every single System of a Down song in only four minutes. Starting with "Suite-Pee," the first track on the band's eponymous debut album, Scallon impressively runs through clips all the way through the final song on the band's 2005 Hypnotize release, "Soldier Side."

"Put System of A Down's discography into a trash compactor and got this," reads the caption on the official YouTube video.

In addition to rehashing other artists' works, Scallon has written a slew of original music as well, in which he uses out-of-the-box instruments such as a theremin, the first ever electronic instrument invented, which is played without using hands. His recent album, The Scene Is Dead, is available now and can be purchased at this location.

During the May 15 episode of 'The Late Show with Stephen Colbert,' Metallica appeared on the show for the first time. The band performed the song "Now that We're Dead," which is taken from their latest release, 'Hardwired… to Self-Destruct.' Video footage of the performance can be seen below.

Metallica had previously made an appearance on Comedy Central's 'The Colbert Report' in September 2013.

HBO's 'Westworld' series is rapidly increasing in popularity among viewers.
