The tracklist of Disc 1 is wrong. The first two songs are arranged versions, look at the CD scan.
I'm not very good in reading Japanese, looks much like track 2 and track 7 from this one:
Garou Densetsu Image Album.
Maybe someone can edit the tracklist, I'm not that much experienced with it
Thanks
PS: I'll check back the other discs too on my copy when I'm back home.
