The problem, Mary, is that you told us about your idea and now, it is
publically noted. I understand your desire to have the music while you
read, it would make it more interesting and artistic, I agree. But, even
music in the background intentionally played will probably violate the
law. You might never be harrassed by anyone, but I would hate for you to
encounter difficulty because of it. The decision is yours, of course, but
my un-lawyerly advice would be to just do the reading.
I know, it is a pain, I sympathize, but they did not ask me before writing the law.
