"Canned Heat" is the second single from British funk/acid jazz band Jamiroquai's fourth studio album, Synkronized, released in 1999. The song was their second #1 on the U.S. Dance Chart and peaked at #4 on the UK Singles Chart. The music video was directed by Jonas Åkerlund. The song is used in the film Napoleon Dynamite, as background music during the title character's famous dance performance before a high school assembly.

Over the numerous releases of the "Canned Heat" single, two B-Sides exist. "Wolf In Sheep's Clothing" is a funky instrumental that features an intro of two drum beats that lasts about 1.5 seconds and then enters a strongly bass driven repetitive melody (which is very reminiscent of "Stayin' Alive" by the Bee Gees). Many keyboard effects are used throughout the song's 4:00 minute duration. The song enters a percussion section at 3:07 and lasts for the remainder of the song slowly fading out from 3:45. The song was originally released as part of the charity album "No Boundaries: A Benefit For The Kosovo Refugees" in 1998, before being included on this single. It is also available on some editions of the Synkronized album, the Australian double disc release being an example.

"Deeper Underground - Chillington Mix" is featured on the second release of "Canned Heat". Chillington is not the name of an artist or DJ, but the name of the studios at Jay's Home in Buckinghamshire. The Chillington Mix samples heavily from the Jamiroquai song Getinfunky which is found on some special releases of Synkronized, such as the Japanese release where it replaced "Deeper Underground" as the bonus track, and alongside Wolf In Sheep's Clothing on the Australian double disc. On the High Times: The Singles DVD, Jay comments on a bonus feature that the original Godzilla song was just made of "Ominous noises" which strongly matches the sound of Getinfunky. When the title or the remix and "Ominous noises" evidence is pared it strongly suggests that "Getinfunky" is an early version of the Godzilla song which later evolved into "Deeper Underground".
