The music for Invader Zim was composed by Kevin Manthei and is in a digital techno style. The title music was composed by Mark Tortoroci, but Manthei arranged it. Manthei, however, did the music for the end credits and all the music for the actual episodes.
In September 2002, 7 months after the cancellation of the series, Anime Stuff-R, an internet radio website, broadcasted the Zim-phony, A 5 hour broadcast of all the music from the 26 episodes of Invader Zim composed by Kevin Manthei. This session, presented by DJ Richard Rae is the most popular that Anime Stuff-R has broadcasted. Also included in this session was an interview with Kevin Manthei by Richard Rae in August of 2002, where Kevin talked mostly about how the music of Invader Zim was composed and inserted in the show.
Because of the popularity of the broadcast, Anime Stuff-R made 100 MP3 CDs with the entire broadcast. They made only 100 because of copyright and financial reasons.
Kevin Manthei also released a Promo CD containing some music from Invader Zim. This Promo CD is still available but one needs to get in touch with composer Kevin Manthei to acquire it.
