FWIW, murrayhill, I think we have come to a sorry state of affairs when our kids think they are entitled to unlimited, free access to the artistic creations of others. If they want free tunes, there's always the radio, tv, web radio, etc. Where exactly do you draw the line between free access and theft? Had all of your work been available without charge and within days of commercial release to anyone with a computer and modem, where would you be right now? A lot poorer, I suspect.
Always tell the truth. Then you'll never have to remember what you said the last time.
