These remixes are just... incredible. Indescribable.
Square-Enix, if one of y'all out there reads this... the next time you remake Final Fantasy IV, you should include these two songs in the game -- possibly even the entire remix soundtrack, though I admit I haven't listened to 'em all.
I can totally see the first song completely replacing its original in the final dungeon leading up to Zemus -- hell, have it override all the random battle music, to make it that much more epic. As for the second... Baron invading Fabul, anyone?
And while you're at it, please make it a multi-platform release.
