Do all Final Fantasy games have a great OST ?

I played FF 13 back in 2009, I remember enjoying it, so I replayed it two weeks ago (it wasn't as great as I remembered) and I also played FF 13-2 (much better gameplay, but not as good a story) and I really, really, really liked the soundtracks, especially the one in FF 13-2, I thought every song was great.

So I was wondering if all FF games have this quality soundtracks?
