Good..I want everyone to get their due but some of these rules, like you lcan't play this at a funeral, or have your radio on in a shop are nuts. If you want your music to stay private, set it up that way and sell to a select few who promise not to whistle or sing it. Once it is out there, to me it is part of the air for the general public anyway..if Nike wants to make a commercial out of it that is a different story..mg
