interjections

I just discovered that 'oh' might probably be the most commonly used interjection in music. Maybe even more popular than 'yeah', although both are oftentimes used together as for example in "Oh Yeah" on the Ferris Bueller Soundtrack or more recently by Housse de Racket.
Check out some great musical evidence:



Say Hi - Oh Oh Oh Oh Oh Oh Oh Oh (mp3)


We Have Band - Oh! (mp3)


Oh No! Oh My! - The Party Punch (mp3)


Oh Snap - Everyone's a DJ (mp3)
