there is only one meaning to lucid dreaming. "you are dreaming, and you know it" if you were hearing the song while you were dreaming, and you knew it was a dream, then yea, it was lucid. if you were dreaming that you were hearing it, but didn't know you were dreaming, then no, it wasn't lucid.

Ya, thats it, You know your dreaming, thats lucid dreaming. There are no others forms.

Lucid dreams can be as real as when your awake. Thats what makes them so cool, except you can go wherever you want, do whatever you want, do anything, anything you can think of.
