Well personally i love gamelan music (and hate Pavarotti) and can listen to it just about anytime. It does something to my psyche that i just cannot explain.
As for wayang, i have only seen short bits of a few performances, though the shortness of my exposure was not due to boredom, but rather because i had other pressing matters to attend to. Personally i don't find any need to fully understand wayang to enjoy it, but i guess i'm funny that way...
