World Class Listening Problem is the fifth full-length studio album by math rock band Don Caballero.

Che remarks that this led producer Al Sutton to say that they were the first band he'd ever worked with who could actually play their songs.

"Savage Composition" and "I'm Goofballs For Bozo Jazz" started as one song called "Heavily Beautiful" (as heard on the Fall 2003 tour), before being split into two.

In a 2006 interview with Resound magazine, Damon Che described "And And And, He Lowered The Twin Down" as "a sequel of sorts," presumably to the 1993 Don Caballero single "ANDANDANDANDANDANDANDANDANDAND".

"Railroad Cancellation" was featured in the season two finale of the FX series Sons of Anarchy.
