euphoria is probably a working title. if she does go with it, it would remind me of things in buddhism and the such where the goal is nirvana, or with jungian psychology (which Joseph campbell bases his work on) is individuation. Both can relate to "euphoria" or being so satisfied with life you are giddy, elated, happy, at one with oneself. However, I think that since she put the "euphoria" in quotes, it's most likely not the title but the feeling you are supposed to get when listening to it.
