Publius,
I agree if you don't only want the technique to work for studying then you let go of the music it pretty quickly. (Baroque music is so easy to let go of. I personally find it as irritaing as elevator muzak) but it does enhance learning and long term memory. In some cases it just helps to make that first leap to get a breakthrough in the techniques - perhaps some people need to grab a security blanket to make it work and let go of it later once the method works for them.
