Meet Chase Holfelder, the genius behind a hauntingly beautiful version of Cyndi Lauper's "Girls Just Wanna Have Fun".

This version isn't meant to depress people (though it might), but it's here to show us that switching to a minor key can affect tone in a major way.

Think about what a fun, upbeat song it is when Lauper sings it. Totally something that would get you up and on the dance floor on 80's night at your favorite local bar. But, when you switch the chord, the song takes on a whole new feel. It's crazy!

Holfelder has also tackled songs like "The Star Spangled Banner" and "Amazing Grace" in a similar fashion.
