I'm currently obsessed with this song (as well as this remarkable cover: Somebody That I Used to Know - Walk off the Earth (Gotye - Cover)
) but it got me thinking about how much I love songs that have this interplay between different characters/vocalists.
Off the top of my head I thought of Nothing Better by Postal Service and Don't You Want Me by Human League as excellent examples. Obsession by Animotion is good as well but doesn't have the same subtle animosity as the other three.
Anyone have any other good songs in the same style?
