Yeah Soukyuu, I agree with you that Whisper of the Land/Twilight Over Thanalan/ On Windy Meadows does have a classical feeling to it. It has a sense of wanting to explore the area, and it fits Limsa Lominsa very well. I think the music for the 3 city-states blend well with the areas. I have the soundtrack (Eorzean Frontiers), and while listening to Gridania's theme, you can hear each and every little instrument that is composed with the louder ones. There is a little sound that sounds like crickets scratching (like, rub your hands together, up and down to get that effect). I don't know what instrument is used for that, but it gave me the feeling that Gridania is a small, bustling town in the woods because of the sound scratching thingie lol

Now the last over world track with the haunting "Answers" really set the tone for the final event. Now that was a stroke of genius on Soken's part!
