For me, i guess, as far as i can remember that it was Elegy. I'm not sure though. What i'm absolutely positive about is that it was the one that really got me interested in him. It was just OVERWHELMING. The PV was absolutely creepy and fascinating, and the song ... omfbbqg, i remember how much i listened to it, and how fascinated i was by it. I was not yet a fan, but this song brought a whole world within it, and i felt totally absorbed by it. *o*
