It's good that Higashino is continuing, even if in a small capacity.
Thanks for the set, Carl!
I must admit I'm also somewhat disappointed. Naoki Maeda definitely isn't on Salamander 2 level with his arrangements, and generally there isn't anything of Sota Fujimori's Gradius Medley level goodness (but when is there?!). But there are also some very good tracks like Hibino's Boost Up, Koshiro's Planet Ratis (that guy still has it for chiptunes!), Yamaoka's Thunderbolt, SuperSweep's A Fighter and Dancing Venus and then Slash Fighter by Higashino herself. So while it's not everything I expected, it's good to see Konami giving arrangements and Gradius music still a chance in the changed vgm landscape.
The original music also has some good ones like Alexandria ~The Pyramid~, both Antarctic tracks and Against Big Boss ~Odin Core~, but the voice sample tracks are pretty disconcerting.
