I have a thing for rock songs that include a piano playing the same note every eighth-note. For example:

• Go With the Flow by Queens of the Stone Age has it going for the entire song.
• The Sweetness by Jimmy Eat World has it at the end.
• Do It or Die by Die Mannequin has it during the intro and chorus.
• In It Doesn't Matter Why by Silversun Pickups, it's not a piano, I'm not even sure what it is, but it's a high pitch repetitive percussive sound.
• Party Hard by Andrew W.K. gets an honorary mention, but the piano note is only every quarter note rather than every eighth note.

Can anyone think of any other songs like this? I know I've heard a bunch, but when I try and come up with any more examples, I can't.
