I feel like anything they replace it with would eventually get annoying.

My fantasy: only ambient noise in the streets, with yard orchestrions that fade in as you approach the yard like seasonal event areas do. *_* I imagine that would set their servers on fire, but a guy can dream.

But yes, tracks that are more tailored to the area or different themes that cycle each day would be nice. I'm stealing that guy's idea to /bgm macro. Brilliant.
