WHOA! This is seriously cool!
A YouTube user basically had a stroke of brilliance when he must have thought to himself, what would Dark Horse by Katy Perry sound like if it were sung by other famous artists?
Well, not only did he think that, but he actually CREATED the song and the result is like nothing else!!
It's basically a GIANT collaboration of Nirvana meets *NSYNC meets Michael Jackson meets SO many more!!
KP's ex-boyfriend, John Mayer, even gets in on the action!
Color us impressed!!
Ch-ch-check out Dark Horse sang in 20 different styles…AFTER THE JUMP!!!
