The artists get nothing from Amazon sales if it is a second hand copy which has been sold. Neither do authors when their books are sold second hand. This is the same in charity shops and other auction web sites when goods are being re-sold. The music and literary industries are trying to do something about it, however, I disagree with fees being paid a second time: they've already had one set of payment for the first copy, and it's the same book or CD being sold. Surely once it's yours you can do what you like with it.
