In "Captain of her Heart" it's the note of an archangel. The first time I heard it, it sneaked up on me and *wham* (no, not the group) it flipped my ecstasy switch.
(". . . she couldn't wait another day for, the captain of her heart")
Some music does that to me.
My wife has that song. It’s okay I guess.
Personally, I like music with flatted fifths much harder and faster!
But maybe I should listen carefully to it- I’ve been trying to figure out a way to sneak that note into the worship music at church.
