Awesome! I can always use another FF remix!
I can't quite manage to hold this much music in my head at the same time after only one listen, but I'll note songs that left an impression on me. Note that I'm not a musician myself, so my reactions tend to be more emotional than technical.
The first song kicks off the album in grand style. I love orchestral versions of video game music, and this could be the opening for a movie.
The "99 Red Ballons" opening in Ana(pro)logue kinda gave me whiplash. Made me chuckle when I recognized it, but it also broke the fourth wall (so to speak) for me. I see what you did there, but... I'm not sure it worked.
RDX Necklace takes an awful long time to get started. I realize the source material doesn't offer much to work with, but my ears just plain get bored by the 2 minute mark.
Just the title of Golbez 'n Goblins makes me laugh.
The harmonies in Fighting for Tomorrow remind me of a hard-to-define Belgian band called "Encryption" I heard a few years ago on Radio Rivendell. Yours is much less repetitive, though.
Rhymes With Elixir is a great entry in the grand tradition of non-serious chocobo remixes. Shiva's line about making you sublimate made me laugh aloud.
Until the Tower Falls is definitely a standout among the instrumentals. The epic fanfare ending is perfect.
I absolutely love the over-the-top "rock opera" feel of Genesis of Destruction. It kind of reminds me of the latter part of "Darkness and Starlight" on Black Mages 3, which you should take as an enormous compliment. I'd like to see the lyrics, though!
On Genesis vs. Phantom, I think the ideal would kinda be a mix between the two (re-remix?). Like as in, the music from Genesis (which I prefer), with the Phantom vocals overlayed on the growly Zeromus noises that are saying the same thing at the same time... if that makes sense. Like "No! Get back! Nooooooo..." overlayed with "Rar! Growr-rar! Raaaaaaaaaaar..."
