Amazon’s Music Storage service will be shut on on April 30th. Here is the announcement from Amazon music
Amazon Music is retiring the Music Storage service, which allows customers to upload and store up to 250 songs in a personal cloud library. Our records indicate you have uploaded one or more songs through your Amazon account in the past.
To keep, download, and play your uploaded songs at no extra cost, simply open a web browser, go to your Music Settings and click the “Keep my songs” button to direct us to save your music to the cloud. Otherwise your uploaded songs will be removed from your library on April 30, 2018.
Your Amazon Music digital purchases will continue to remain securely stored for playback and download — no further action is required to retain those. These changes will not impact your ability to stream Prime Music or Amazon Music Unlimited.
