A mindless epithet given to those musics where they play "too many" notes. I think the term is more applicable to pop music and similar types of aural wallpaper. What is masturbation? From the hypermoral POV, it's sexual activity devoid of redeeming content - no sex partner, no context within the Sacrament of Marriage; no real love. Corporate-driven musics are also lacking in content; they're designed to be consumed rather than listened to, and are about instant gratification.
