I’ve always been impressed by mashups the same way that a cave man would be impressed by a flashlight.  I have no fucking idea how music works, so to me, mixing two different songs together is pretty much voodoo.  Well the Australian comedy group Axis of Awesome (epic name, BTW) just took away some of the magic.  As it turns out, about half the pop songs ever written use the same four-chord progression (fun fact - they’re all ripping off Pachelbel’s Canon in D).  In this bit, they string together several dozen of them in a four-chord medley of win.  Now, off to the internets to find more stuff from these guys!  (via Digg)
