The Axis of Awesome - "4 Chords"

The four chords that are used in Journey's 'Don't Stop Believin' are (of course) used in a ton of other songs. To see just how many, watch The Axis of Awesome's '4 Chords'. It's a pretty nice montage of pop songs that use the same four chords, and it's well put together. It's not a conspiracy or anything. A limited number of basic chords exist, and these songs share the same ones. You could do the same with any four chords, and it would include an astounding number of songs.
