Kick it to....overdrive!!
Like the slow start and then the full song just picks up. I think it could make some nice level music for traversing Cloudsdale or when you possibly encounter a boss near the later half of the game who has more of a speed related strategy of trying to win and defeat you which makes your timing very critical to win in the battle. Very nice yet awesome boss song for kicking into overdrive too!
The synth was awesome and the synth solo was pretty fun to hear in the later part of the song as well I think. The guitar synth was nice on the ears and gave a feel of trying to rock out a bit. Then the classy sounding synth reminded me of Chemical Factory zone 1 from Sonic the Hedgehog two which wasn't all that bad of a game.
The angelic synth is very nice and gives a feeling of hope as the boss gets faster and more desperate in its attempt to defeat you during the fight for eternal night time possibly. The drums and bass were both incredible and well done too. Very well done song!
Overall, rather enjoyable, awesome boss like song!
