Mine would have to be Bloody Tears, Moonlight Nocturne, and the Title Screen song from Simon's Quest (still scares me just as much as the music from the NES friday the 13th). The BT from the end of Aria is sweet, but nothing gives more chills than the one in Simon's Quest. Also, wtf wasn't there a version of bloody tears in SotN?
The Prayer and similar piece in Circle of the Moon are also really pleasant.
