Up until I was about 8 or 9, I was convinced that, if you were a pop band, or any kind of band, ALL of your songs had to have roughly the same time signature. That was the rule! I guessed that bands split up most often because one or two of them wanted a change of sound. This belief probably arose since I was listening to The Spice Girls and such at the time, and their music doesn't exactly have a lot of variation.
