All twenty-five songs from the iconic DJ Earworm mashup, United State of Pop 2009, as well as said mashup. I tried my best to put the songs in order of first appearance.

NOTE: I am NOT planning to make playlists for the rest of the year-end mashups. I chose to do this one because it is my very favorite of them. So, don't ask me to do the rest, because I won't, but maybe you can.
