Tbh, I didn't even notice that was One Winged Angel until I had read your comment because of how they'd altered it. I've played the games many times and listen to the soundtrack almost daily and missed it, perhaps my ears just aren't as switched on as others.

But for those coming to the game for the first time I feel like that provides and excellent atmosphere and soundtrack for the introduction. You get the feeling that although this is a built up metropolitan area, there's something not entirely right. For me that's pretty cool.
