I wonder how many people have read Amazon MP3 Music Service: Terms of Use
"Except as set forth in Section 2.1 above, you agree that you will not redistribute, transmit, assign, sell, broadcast, rent, share, lend, modify, adapt, edit, sub-license or otherwise transfer or use the Digital Content."
In other words, it is illegal to SHARE or even lend your music to someone else - something that you can even do with physical media. Interestingly enough, the itms makes absolutely no claim about sharing or lending music, either in Fairplay or non-DRM music. http://www.apple.com/legal/itunes/us/service.html
I just wonder how many people will be breaking the legal contract between themselves and Amazon.
