Ahh...
I absolutely loved this tune in gravitaxis, and the animation too. This song just made it perfect.
I downloaded this song after seeing gravitaxis, and I still listen to it all the time... The feel is very soothing, and it feels like a happy tune to me, even though it is somehow very emotionally charged... All I can say is that it's a beautiful track, and one that I will come back to over and over without tiring. ^^
