Final Fantasy!

No, this has nothing to do with either Final Fantasy 7 or Final Fantasy 8.

Well okay, in a form it does, but I'm not talking Steam here.

Actually, what I wanted to know, was to any of those out there who have played any of the games (Or all of them like I have), which ones did you find to have some of the best music or most memorable(And I mean game wise, and not just for a few songs).

Feel free to even list what version (Since chances are, newer versions have had upgraded music, like from the original Final Fantasy for NES which I own to just the Wonderswan version, which upgraded all of the music, and even added in some more, changing the final boss fight from the original battle theme to the very first Final Fantasy epic final boss battle fight song)

To start it off, while I really like most of the music from all of the games, I find the music from Final Fantasy 5/V (PS1 version) the most memorable, and probably some of the best.
Chances are, when Final Fantasy music just seems to edge its way into my brain, it actually tends to be from 5.

TL;DR: LIST THE FINAL FANTASY GAMES THAT YOU BELIEVE HAS THE GREATEST/MOST MEMORABLE SONGS.
