VG music that is hauntingly beautiful.

Terranigma - Underworld

Imagine this music being performed by a whole orchestra. So beautiful and sad at the same time.

Also, I love threads like these. I always discover awesome tracks I did not know about!
Man Terranigma was great, the whole game fits the description "hauntingly beautiful". I love melancholy, but it's rare that a game or music can really pull it off. Terranigma and the Mother series (especially 3) are some great examples of it being done right.
