From the cute little game, which can be downloaded HERE (http://intihuatani.usc.edu/cloud/) for free, the very relaxing music.
Cloud is a game about a hospitalized boy daydreaming to fly around and control clouds. A very cute and beautiful game. =)

The file format is OGG.

Though I didn't play it myself, I saw "Cloud" at E3 last year in the indie games section. It was very interesting. Thanks for the upload (and thanks for your comment on the album I uploaded, too).
