In these Conan albums, do the voice actors & singers really compose and arrange part of the soundtracks, and are the Japanese titles hardly available?

There are many singers out there who compose music and write lyrics, but
"Boku ga Iru" is composed solely by Katsuo Ono, and Iori's role was just the singer, for instance.
