Hehheh, the nerdcore is finally happening :)
And it's even nerdy XD
I wouldn't worry about about any mods removing this and banning you. It's quite obvious that it's legal by the license standard, especially with that description ;)
Now, on to the piece.
I really love it! It's clearly one of your very best tracks. I guess it may help that you got to use melodies that you already knew were great, but still, you had to learn them by ear :p
It would seem you've mashed a couple of songs at a few places too, to get a smooth transition. I'm basing this on your timestamps though. Well, I suppose you could've miswritten some of the timestamps as well. I haven't listened that much to the GD songs, apart from Step's and Waterflame's stuff. I now realize I should o.O
Really good job with Polargeist. I have to assume that the rest of the songs are as great compared to the original too. Even if they wouldn't be, they are already great. All the harmonies between the chords, intruments and melodies are great, so whether it's exactly the same as the original or not doesn't matter too much.
I'm really impressed by all the transitions! The flow is ridiculously smooth, and you've almost got 20 different songs in here :O
As usually your percussion work is all but unimpressive. The mix is smooth, and pretty amazing considering there were so many different things to fit in here. Now you made me want to do a medley sometime! Probably a Final Fantasy 7 medley... Oh yes... My heart wants it...
I don't have much else to say, especially since I haven't heard all the individual songs. But once again, the quality is great. You are right to be proud of this :3
UltrAmazing work dude(exclamation mark).
Favved in an instant :D¨
Keep it up ;)
