Paul Hardcastle and Simon Fuller produced the first soundtracks for Bionicle's commercials used in 2001 to 2003. Music for the first three Bionicle films featured a more classical tune, rather that the techno-like beats used in the ads and animations. In 2005, the first official Bionicle songs were released. They were produced by rock band All Insane Kids and are called "Hero" and "Caught In A Dream" (the latter being used as the theme of Bionicle 3). Further down Bionicle's history, more songs were used to help advertise their sets, most of which were produced by Danish band Cryoshell, as well as songs by other artists, like "Crashed" by Daughtry and "Move Along" by The All-American Rejects.
