Gregorian Chant WITH fast Techno effects!
Fast woodwind section. Panpipes, quick shuffling dance music.
Very slow, dramatic music. Slowly crescendos into a very loud climax or something.
Death metal interspersed with requiems?
Rock!
Steve Reich & Phillip Glass-esque music.
Looping, random noises, et cetera.
Anything very emotional, passionate, and powerful. Rock and maybe alternative works.
Percussion and brass section.
Umm... country?
Clear melody and harmony, yaaay.
Epic harps and organs with classical and baroque music.
Oldies, as previously suggested.
Mystical techno with underwater sounds like Scaredgirl said.
