HECK YEAH Mega Man X music! Although I must admit that Launch Octopus is one of the Maverick stage themes that I am not that familiar with. My favourite part of the original is definitely the orchestral hits. While your remastering of this seems to make those hits a lot less subdued, you make up for it with really good bass. I LOVE how pronounced it gets at the beginning. I do agree that the guitar, especially towards the end gets too loud, but it sounds pretty accurate to the original piece besides that, instrument-wise.
I'm completely biased, but I'm very happy to hear a Mega Man related piece entered into this compo. :D
