I've owned this album since it came out in 2014, and my backlog is such that I've finally started listening to it. First, Gunstar Heroes is an album that I regularly listen to. When I open foobar and grab music, I tend to pick Gunstar Heroes a lot. It wasn't always this way. I neglected it for many years and someone requested a CD-R within the past few years, so I "rediscovered" it.
Last night, I listened to the Gunstar Heroes OST for the first time. I was very entertained, which was due to my extensive exposure to the arrange album.
The other soundtrack of significance on this album is Alien Soldier. I haven't yet listened to it yet, but I own Alien Soldier and I'm looking forward to making a comparison.
And where's Vol. 2?
