Basically, all the 'AutoRip' music you’ve bought from Amazon for the past 17 years is sitting online, just waiting to be streamed or downloaded. Head on over to the Amazon Cloud Player to check it out.
The Amazon Cloud Player is entirely free to play around with, and invites you to add a further 250 tracks. All Amazon digital music and 'AutoRip' purchases are available automatically.
Heck, I just signed in and found 70 albums waiting for me. Sweet! Now I'm off to install Amazon Music from the App Store, which means I can stream my stuff on the move. Android peeps can do the same with the Amazon Music with Prime Music app.
