So there's this dude on YouTube, a really talented musician, who re-records famous songs and switches their genres around. It's usually as extreme a change as possible, like his "Radio Disney" version of a Cannibal Corpse song called "Hammer-Smashed Face," or this metal version of a Jonas Brothers song --

My favorite might be the "smooth jazz" version of "Enter Sandman," though. I love how pumped the fans get at James Hetfield's laid-back guitar riffs!

Or what if Lady Gaga's "Poker Face" became ... wait for it ... POLKA face?

Louis Armstrong seems possessed by Satan in this metal-edged perversion of his most famous song.

Here's Slayer's "Raining Blood" if the Jonas Brothers recorded it.

Disney Slipknot! Yikes, they're still scary. And sweary -- some NSFW language here.

You get the idea. Fun stuff! There's lots more where that came from, including a reggae version of "Detroit Rock City," on Andy Rehfelt's webzone.
