If I had a nickel for every two-hour video essay I've watched this weekend about searching for the creator of an obscure musical tone or sound, I'd have two nickels, etc etc

but it's so funny how the Hbomberguy one was just kind of maddening and the Defunctland one was really emotional and heartwrenching

What was Defunctland's?
I hadn't seen anyone else mention that one yet.

searching for the composer of the Disney Channel bumper jingle

the little four-note deal that plays with the "you're watching the Disney Channel!" bumpers

Ahhhhh.
