Umm sir. I think this is quite special. :) This was a great tune, sad in the game knowing Yuna's fate, but I loved the music they used. This is very pretty and good indeed.
I honestly can't say I know much about the game since I never played it, but if you enjoyed what you heard then I'm happy about that.
Please contact me if you would like to use this in a project. We can discuss the details.
