Aside from some AC tunes, I've also sneaked in a few from other Final Fantasy games - in PSF format! (Everything FF7 - FFX-2 comes in PSF audio!) For perfect, small filesize looping! (For miniPSF's just copy the psflib file into the directory as the PSF itself).
Namely, I've replaced Prelude with the FFXI Prelude, 'Underneath the Rotting Pizza' with 'The Spy' from FF8, 'Buried in the Snow' with 'The Salt Flats' also from FF8, along with replacing the battle theme, and victory fanfare, with that of FF8 (The FF7 one really hurts my head after a while, and the Piano version, while absolutely lovely, just isn't fitting for some battles - I'm also a bit of a FF8 fan, so pah!), 'Hurry!' and 'Hurry Faster!' with 'Hurry' and 'Attack' from FFX, and the Bizarro Sephiroth (Safer got the AC OWA treatment) tune with 'Decisive Battle' from FFX. I've also changed the regular Boss music to the Black Mages version of the FF8 Boss music (personally, I always thought that beyond the initial guitar-riff of the FF7 version, the tune itself was pretty weak). Having a gander at my folder, I've also changed the Northern Crater (Judgement Day) music to "Across the Divide" (MP3) of FF:CC. It's a very charming, and different, experience going through the crater to Sephiroth!
I've also dumped 'Twinkle Park' (Mp3) from Sonic Adventure in as the new Gold Saucer background... I just had to put anything in there, I really can't stand that doo-doo-doooo of the regular Golden Plate. And it isn't all that shabby, really!
