When you consider two markets a) digital content sales (amazon mp3 store) b) paid cloud music host for pirates Selling MP3's is clearly a superior business, and they are to some extent at odds with each other. What's more, we know that Amazon has contractual relationships with the majors and plenty of other music players. If they defacto condoned piracy they could end up getting a lot of grief over it from their partners. Note that storing your pirated files on the service is against the TOU: You must ensure that you have all the necessary rights in Your Files that permit you to use the Service without infringing the rights of any copyright owners, violating any applicable laws or violating the terms of any license or agreement to which you are bound And they have the right to inspect your files to ensure, among other things, your compliance with the TOU: You give us the right to access, retain, use and disclose your account information and Your Files: [...] to investigate compliance with the terms of this Agreement, enforce the terms of this Agreement Whats more, the way music is commonly pirated means many illicit copies will have very common and identifiable names and hashes. The way amazon will be doing de-duplication means they'll automatically have indexed lists of every user that has a copy of each file without even trying to make one. While I'm unsure if they'd want to do anything about it for PR reasons, given their interests and those of their partners I certainly wouldn't suggest using Cloud Drive for files you don't have legitimate rights to. In a bit of an unlikely what-if scenario, imagine Amazon + Warner Brothers offering you a one time chance to pay $3000 to buy all the questionable music in your account or they'll refer the matter to their attorneys?
