I personally think that weird time signatures might add different elements to music, but could also distract the listener (sp?) to the music at hand.
For example: Norma Jean and Tool use weird time signatures, and it seperates them from alot of bands out there, but sometimes u feel that the music can sometimes feel too out of place if u understand what i mean...and i was wondering if the same thing applies to orchestra music?
just let me know your thoughts on this...
