Number 2: I GOTTA FEELING The Black Eyed Peas

This track is no verse-chorus song, yet if you look at the form it is. Curious ain't it? It's definitely ABABCBA, but instead of the B section being the chorus, they've made the A section the chorus, and instead of closing with B, they repeat A again. Simple idea. Damn I wish I'd thought of it. Never mind, it's abstract enough to re-use. Full marks to the Black Eyed Peas for producing a track that's fun and fresh.
