Legal Question in Consumer Law in Texas

Generally, a business has the right to play any kind of music it wants to.

But your contention would be: I signed up for a gym membership; I didn't sign up to be evangelized. You should write a letter (a PAPER letter, not an email, and don't make any phone calls): "I hereby cancel my contract effective because you have created an environment where it is impossible for me to enjoy the benefits of club membership, and therefore you are not performing under our contract. I have told you repeatedly that I do not listen to religious music at home, and do not want to be in a place where it is played, and you nevertheless persist in programming this type of music over the speaker system at your facility. Because the breach is yours and not mine, I will not pay a cancellation fee."

Send this letter to the main address, and if you have any other addresses (corporate office, etc.) send a copy to each such address. Keep a copy for yourself. Just for fun, show on the letter (at the bottom) that you have also sent a copy here:
