NOTE: This album also includes the mobile versions of the music and SFX. So there was either a mobile version of the game that we did not know existed, or they exclusively made it to pay homage to old mobile devices.
I have to get this off my chest.

I took a listen to it today after getting it from ffshrine, and it just took me by surprise!

I know, we already have the arranged Starblade soundtrack, but the one in the NAMCO Game Sound Express was a little different than the one heard on the Laserdisc, unlike this latest album, which has arranged tracks (Laserdisc Version), not to mention the previously unreleased "CHARACTER SHOW".
We could label the two of them... Starblade (NAMCO Game Sound Express ver.), and Starblade (Laserdisc w/o SFX edition).
One thing bad about this album, however, is that they used the VOICE sounds from the arcade PCB boards (Therefore very low quality), compared to NAMCO Game Sound Express using the masters for the VOICE lines (Therefore... well you get the idea).
I think we should expect Vol. 6 to do GALAXIAN3, previously unreleased tracks, and (again) Laserdisc versions.
