when you publish a song it is not yours anymore. unlike a car this is non-materialistic property you can't hold it in your arms and say "it's mine". and that's what it's all about.

think about my idea as intelectual communism. "open source playing" is not about taking others' ideas is about sharing your ideas with others and in the ideas flow get new ideas. it's not about selling music so nobody else could sell it it's about not selling it in the first place. the only thing that keeps us from doing that is norms. i say break'em!

you can BUY a record hear a song, BUY it's notes (or get it's tab by yourself or the net but you're never sure it's corrct), play for yourself, play it with friends but not on stage. you can't copy the disc, you can't broadcast, play or rent it. you can't say "i think it would sound better if i chage this note" call it "Stairway to Heaven by Led Zeppelin (modified by Psycho Amram)" and spred it. you can't share with the world your way of playing it.
