"Copyright law requires a balancing of the interest of copyright holders against the rights of everyone else. Artists are entitled — despite the arguments of Napster and its defenders — to a property interest in their work for a reasonable period of time."
"But the public also has an interest in seeing that copyrights eventually lapse, and that creative work enters the public domain with no need to pay royalties. Contemporary artists are then free to borrow from these older works, a creative tradition that dates back to the ancients."
