Of course, blending sounds together gives you more music, but you can also dovetail some plots. For example, the movie Crossroads (With Ralph Maccio, not Britney Spears) gives us the Devil, selling souls for rock-n-roll, voodoo charms... magic, music, and a general atmosphere that screams Shadowrun *without* using cybernetics or computers. Seriously.

Unplugged, as it were.
