You could also use FFmusic to make FF7PC play mp3s, meaning you could just obtain the OST and it would sound identical, or get some nice remixes and make it sound even better. But until Ficedula fixed the looping of mp3s in that program (which seems like, never), you`d be content with only hearing it once... Even then I suppose you would have to tinker around to make it loop at the right moment, which would be time-consuming.
And naturally you would get vocals this way.
