Here is the soundtrack to Lamberto Bava's 1985 splatterfest DEMONS. Demons is to me one of the perfect party movies. Some parts of it defy all known conventional logic, but thats okay because it is total non-stop carnage propelled by a soundtrack that is equal parts Claudio Simonetti (of Goblin fame) electronic score and equal parts 80's heavy metal and "new wave". Bands included on this soundtrack, in case you didn't know, are Motley Crue, Accept, Saxon, Scorpions, Pretty Maids, Rick Springfield, Billy Idol, Go West, and The Adventures.
Demons - A Non-Stop, Merciless Gorefest. Check it out.
