Listening to Instrumentals of pop songs is COOL

So I first noticed how cool it was when I first listened to Dynamite instrumental. The chorus was the backing for the verses. I had never noticed that before (it mightve been the other way around, or both ways, anyways). At one point I noticed the background ping pong noise in life goes one (thought other people pointed out it might be a metronome). Recently I noticed this clashing vocal "ah" in the second and third chorus of Black Mamba...and I'm OBSESSED. It has this crunchy awkward feeling, and it's just so unique and good.
