In my day, possibly dirty lyrics were slurred and mumbled so as to leave a little mystery (remember "Louie, Louie"?), not to mention some plausible deniability if mom or dad asked, "what did he say?" The problem with music today isn't that it's filthier; it's that it's too clearly enunciated. Thank God my daughter protects my tender sensibilities by changing the car-radio station before I hear something I shouldn't.
