I searched but all I could find were imports of the soundtracks from Japan. The main soundtrack is this one:

Obviously most of the songs on there would be instrumental anyway, since they are the background music from the game, apart from Real Emotion and 1000 Words.

They also have the Vocal collections but I can only find those in Japanese too, this page has a full list:

This page also shows all the different soundtracks which all seem to be Japanese:

I think usually only Japanese versions are available of the FF soundtracks - correct me if I'm wrong, although Kingdom Hearts had a US release.

If it's just the main game music you want, I'd say just buy the soundtrack anyway, since there's only two vocal songs on it as far as I know (which are pretty good in Japanese anyway) you won't miss out on much and can always download the english versions of Real Emotion and 1000 Words if you want those too.

Hope I was some help. =)
