Dark, haunting, and chilly are all words that come to mind listening to the track "Dead Bodies Floating On Water" by the Norway project IMMUNDUS. Constructed in the Ghost Ambient genre, the synthesizer and electronic music combine with the murky sound of rain falling in a swamp to produce the eerie effect intended. This one is definitely not one to fall asleep by...especially if you're afraid of things that go bump in the night.
