Amazon launched a new service called AutoRip that will start offering free MP3 downloads of any CD you buy from the site. But the really interesting part of the new service is the fact that it will give consumers MP3 versions of any album they’ve purchased from Amazon in the last 15 years. AutoRip will link to 50,000 albums and counting, and users will be able to listen in the cloud and/or download digital copies.

Any Cloud Player-compatible devices will play the music, including Kindle Fire, Android devices, iOS devices, Roku, Sonos and Samsung Smart TVs.

“It’s already been activated and, better still, our previous music purchases are already on the Cloud Player ready to go — no confirmation needed,” reports Engadget. “We did note however, that some of our more obscure albums didn’t transfer in full — in some cases only half the tracks made the transition.”

“Customers who have purchased AutoRip CDs from Amazon dating back to 1998 will find free MP3 versions automatically added to their Cloud Player accounts — free of charge,” notes the Amazon press release.

“What would you say if you bought music CDs from a company 15 years ago, and then 15 years later that company licensed the rights from the record companies to give you the MP3 versions of those CDs… and then to top it off, did that for you automatically and for free?” said Jeff Bezos, Amazon.com founder and CEO. “Well, starting today, it’s available to all of our customers — past, present, and future — at no cost. We love these opportunities to do something unexpected for our customers.”
