The difference is that they think they can get paid when Amazon sells the song to you and when Amazon rents the hard drive space to you and when you stream the song from Amazon and when you send a friend a link to listen to a song and when you try to download the song again after your hard drive in your home computer dies and when you try to listen to a song on a phone and when you try to listen to a song in a broswer and when you have more than 1 device that can listen to the song at once and when you upgrade computers and when you apply a software update to your phone. tl;dr there are a bunch of old people that have no idea how the music industry works anymore negotiating with the companies that are their only hope for keeping them in business.
