I want to download Haunting Ground (Demento) soundtrack.

But all I can do is "Save link as..."

Then I get a file that is supposed to open with iTunes. But when click it twice to open it, the iTunes program opens but nothing else happens. There isn't a song on iTunes list... It's like a ghost file or something.

Could someone please tell me what's wrong?? Is it possible to download this OST or not??
