I love a pop culture piece that mentions chord changes.
Jingle Hell - The diabolical geniuses behind Subway's "five-dollar foot-long" song.
"The chord structure does imply something dark," he agreed. "On the word long, it goes down from a C to an A-flat which is kind of a weird place. It's definitely not a poppy, happy place. It's more of a metaly place. But at the same time, the singing stays almost saccharine."
