[3] Most songs on the album were written by Alf Clausen,[1] who is the composer on The Simpsons and co-writes, arranges, produces, and conducts almost all music that is featured in the show.

AllMusic's Stephen Thomas Erlewine gave the album a five out of five rating, writing that "it serves as a reminder of the sheer brilliance of the music within this peerless show.

In 'The Simpsons Spin-Off Showcase' medley, the 'Chief Wiggum, P.I' cue was great invention in the style of Jan Hammer's original orchestrations for Miami Vice.

She wrote that "this showcases the brilliant work of series composer Alf Clausen and his delightful knack of spoofing various musical forms.
