Why aren't songs with 11 beats 13 beats, common?
I wonder why haven't I heard songs that have 13 beats or 11 beats (or may be 17 beats or other complex number) per measure. Are there any songs like that and why don't people and music directors create songs like that? Is there any rules not to create songs like that, or they don't want songs to be too complex? I have heard songs up to 7 beats though.
