Musician Charles Laurita created this toned-down rendition of our favorite seedy space-bar music.

When you're covering Metallica as a harp duet, picturesque desert scenery is pretty much required to make everything perfect.

The song is "Nothing Else Matters," by the way.

By the twins Camille and Kennerly, known for tackling such nerdtastic standards as the Legend of Zelda soundtrack and Game of Thrones.

This, kids, is what adults call "globalization."

This one-string cover is meant to less the guitarist's skill than how generic and simple Asking Alexandria is.

George Dennehy's performance of the Goo Goo Dolls at the Strawberry Faire in Ashland, Virginia, using only his feet, won him a scholarship to major in the performance arts.

Anyone who makes any inappropriate jokes about this amazing feat is the most heartless scumbag in the world, hands down.

They might be playing a song you've heard a million times before, but The Piano Guys milk so much musical sound out of one piano (recalling the five-person-one-guitar cover from last February) that it's well worth your while.

We know, we know. You've heard both of these songs a million times before, and not even an adorable mashup of the two by Pomplamoose might keep you from rolling your eyes and saying "UGH, not AGAIN" (did you do that? Be honest!) But this arrangement is executed well enough to be worth your time, and the music video defies the obvious visuals by paying homage to the 2009 thriller "The Box" (or possibly "Button Button" by Richard Matheson, the short story on which the movie was based).
