My sound system is currently disassembled, so I've not been able to properly listen to this, and I don't want to make comments based solely on looking at waveforms, but it seems to have good sound quality. I like how she doesn't load up her music with heavy instrumental. It's light and crisp all the way.
I suppose I should've listed this under the anime title, "Super Robot Taisen OG - Divine Wars" to keep things more consistent, but oh well.
