There's nothing like a good chase song, and The Go! Team's masterpiece, Junior Kickstart is one of the best. It's a great song from top to bottom, but the just-slight-low-fi-but-not-too-low-fi production value just rounds the whole thing out perfectly. It's definitely one of my favorite "harmonica and horns" jams, and on the list of songs I'd want to start playing if I was running for my life.
As a bonus, this Ms. Pac-Man that's been paired with it is superb. Her spin move is second to none.
