I compare songwriting to childbirth. How many kids can you have before your uterus explodes?
Billy JoelEverybody is different. Some writers can write reams of great books and then J. D. Salinger wrote just a few. Beethoven wrote nine symphonies. They were all phenomenal. Mozart wrote some 40 symphonies, and they were all phenomenal. That doesn't mean Beethoven was a lesser writer, it's just some guys are capable of more productivity, some guys take more time.
