I think you're underselling where we'll get to in the next 5-10 years. I'm thinking:

Best Beatles song recorded between Rubber Soul and Revolver, composed mainly by McCartney but Lennon wrote the bridge and Ringo was feeling adventurous and Harrison was angry that day, and it was deemed not commercial enough to include on Revolver.

Best season 3 episode of The Simpsons, really showing the transition to Homer as the lead, written by Robert Cohen with significant musical input from Danny Elfman and featuring seven characters loosely representing the deadly sins, with Homer as Gluttony of course.
