I did this Wretches and Kings/POA mashup thing a little while back I think sounds pretty cool.

Similar to how Mike did little Fort Minor snippets over Points on the Minutes to Midnight Tour, but with a twist.
The awesome rap verse at the end of And One could always be used as an intro to something, perhaps Waiting for the End?
