I personally find it more effective when there is background music in a hypnosis file. It seems to me that the background music distracts me justs enough to keep me from being completely distracted, from the hypnosis session, into thinking about unrelated things and ignoring the session.
What do you think? Is background music beneficial to you, or not. Clearly, I can post a voice version first, and add music later, and post the second version. So I am mostly curious.
