The music in Platypus on all platforms (except for the iPhone port) consists of various remixes of Commodore 64 game tunes by various composers, and created by several artists. They originally appeared on CDs from the C64Audio.com label, and were licensed to Idigicon Ltd. by High Technology Publishing Ltd.
The current publishers for all composers whose music appeared in the game except Jonathan Dunn who is represented by Bucks Music Publishing Ltd. and who at the time was unpublished. Where possible, full credits appeared in the distributions, albeit in text file form.
