Well, here's a scheme they could use...audio watermarks in the downloads.
To buy the song, you must provide credit card info, home address, phone number, mother's maiden name, name of your first dog (or other pet), most embarrassing moment, and other pertinent data. Wait three days for confirmation of information and voilÃ , you can hear your music.
If the song finds its way online, the individualized watermark placed in your copy of the music leads directly back to you! Then the RIAA goon squad pays you a visit. :eek:
