Eureka 7 isn't a band - it is a tv show (aka Psalms of Planets Eureka seveN) so update your tags to reflect this.
Eureka 7 tells/shows the story of a kid named Renton Thurston and the outlaw group he joins: Gekkostate, his relationship with the Nirvash pilot Eureka, and the secrets of the Coralians. So in other words Eureka 7, didn't write these songs they were just used on the show.
