I've found that the musical scores for older Italian thrillers are very appropriate for fantasy gaming. Goblin's title track for Dario Argento's Suspiria is, for example, perfect for any game (or game session) that deals with witchcraft, while songs like Le Notti Erotiche dei morti Viventi (a bonus track on the Joe D'Amato Antropophagus soundtrack) work very well for high tension action. Ditto the repetitive Metropolis from Stelvio Cipriani's work on L'invasion Des Zombies.
