We thought this combination of artists had the Most Random Collaboration of the Year title in the bag. Not even close. The bluesy rock frontman that brought us The White Stripes and The Raconteurs has gone and linked up with fellow Detroit weirdos Insane Clown Posse.

To top it all off, the song is based around a lost piece of music written by Mozart. Oh, and the title is "Leck Mich Im Arsch," which literally translates into "Lick Me In The Arse" (yes, Mozart actually came up with that title).

This is too strange to even try to explain. Just listen below.

Listen: Insane Clown Posse "Leck Mich Im Arsch"
