[CHz]

I found more credits on old versions of High Kick Entertainment's site for this (and also how many songs Nao Harada and Kentaro did for Scared Rider Xechs, no specifics though). It's possible that Harada, Tada, QuinN, and Kinoshita did more songs. There may be other composers too, although those four are the only ones from High Kick who participated.

I removed Abo from the "Theme of xxx I -Prechange-" songs because the songs he lists actually have the subtitle -Mismatch- and I'm not sure that those aren't actually different songs. He lists several other songs that also aren't on this album either so it doesn't appear to be a complete soundtrack.
