The Soundtrack to Silent Hill 4 is available to view, it comes On 2 cd's, CD1 has 22 tracks and CD2 has 12, the track listing for CD2 is in japenese as is the site since it's on part of Konami's site, but the track listing for Cd1 is in english and you can preview a few of the tracks, being just a preview they only last a few seconds and it plays using Flash player, but you get the idea of how the soundtrack is going to be, Silent Hill imo has always had a good soundtrack with all their games, and this to me is the best, check it out using the link below.
