"38 Ghosts" is a hidden track of 2008's Ghosts I–IV, found exclusively in the Multitrack DVD in the Deluxe Edition. The track has not been released in a song format, instead being only officially available in multitrack form for listeners to put together themselves. It bears a strong resemblance to the song "Demon Seed" off of the album The Slip. It is possible that this could be a demo for "Demon Seed" or the drums from "Demon Seed" could have been borrowed or inspired from this song.
This is the only known version.
"38 Ghosts" has never been played live.
