I skipped around and it's generally too noisy for me. My hearing is pretty sensitive when it comes to variance in volume and stuff. The various ___core stuff tends to give me a headache, seriously.
I guess if I were to pick a song I liked it'd be the Megaman remix at 18:18. I'm trying to remember what stage theme it was. Bubbleman? I think I'm so old for the genre that I recognize the songs that are supposed to be unknown.
