Naiad's dance was going to be my favorite but Surfing the Chromosphere was really really good. All of the instruments were really good and it had energy which I like.
I much prefer fun and energetic songs so I was glad when those 2 songs came in because I was worried it was all going to be very samey with ambience. Having those tracks fleshed everything out and made it feel like a real OST.
I wrote those 2 paragraphs as I listened clearly because Back to blue was also really good with its speed and energy mixing the great piano with the intense percussion section.
I was pleasantly surprised by this whole soundtrack. I expected 6 very slow songs after the first 2 tracks (Which weren't bad just not my style) but then the rest were super good and turned my expectations around. Great work!
