"-Silent-" is the first of three hidden songs in the second disc of the deluxe edition of .5: The Gray Chapter. This song is exactly 2 minutes of nothing but silence. According to some of the band members, they put this track in for two reasons. First reason was to have a gap between the end of the actual songs and the hidden tracks. Second reason was that those were two minutes of silence in honor for their fallen band member, friend, and brother Paul Gray (#2).
