I suppose it's considered wanky, but I seem to have an obsession with chord changes and their impact. (And then about once a year I start variations on this wanky thread.)
I think this hit home to me when I was talking to someone about the way some songs frustrate me because the first time you hear them, you can heard the chord they *should* go to, maybe at the end of the chorus, and then they don't. And their response was sort of, WTF, songs are just songs. As if they arrive fully formed and never could have been any other way.
And maybe you'd think this is just the difference between people who understand how music is put together and those who don't. But I don't think it is. For example, it strikes me as incredibly odd that bands don't change songs this way more often. It seems like everyone just writes songs and then consider them structurally perfect upon completion. Isn't that strange, in a way?
Lawson - Standing in the Dark (1.21-1.25)
Black Eyed Peas - Meet Me Halfway (1.03)
Now clearly, these are pretty terrible songs. But there's something in those bits that does something funny to my brain, and no amount of crass sentiment or over-production can halt that.
D'ya know? Maybe not. Never mind.
