I love FF6, and I was very excited to hear this, but I honestly feel the soundtrack is a mixed bag. Some of the tracks are fantastic, and they really hit the opera scene out of the ball park. Another favorite is the ever emotional Forever Rachael, which comes across as hauntingly beautiful.
On the other hand, I felt that many tracks deviated too greatly from their original tunes for my liking, and the whole soundtrack lacked a certain "punch" with the remixes of Dancing Mad and the Credits themes both seeming weaker than they should have been. Even so, this is an amazing fan effort that everyone should check out.
