Favourite OST / Song?

[Chibi Altaria]

This goes for both games, movies and anime, or whatever!

I CAN'T CHOOSE, IT'S SO HARD. ;n; I have too many anime that I watch, so that's out haha. I really like anything Nobuo Uematsu makes, though (most known for Final Fantasy). To that end, I really love the FFX Soundtrack. And on the OST, probably To Zanarkand would have to be my favourite.

Currently I'm into the Undertale OST. Haven't played it? PLEASE DO. It's just so awesome! >u<
