personally, i think we just should air music depending on each elements mood. for example, fire would have rushing tempo, life should have music that gives you this tribal feeling some "back to primary instincts" tempo. for water, i suggest something easy to listen, something soothing. death... some freakin' slipknot will do the trick (lol). darkness, i guess heavy metal could be used. time; classical music and the occasional sound of a clock would do good, for aether, something trippy, to detach the listener from earthly reality, earth; bass and drums. for entropy, im thinking of techno music. light... chorus and the haleluyah song. gravity; something heavy, but not too much, just heavy enough.
those are my suggestions for music
