It looks like JRiver could play the whole audio library worldwide. But does it play Amazon Music downloads? Unfortunately, the answer is NO.
Amazon Music, one of the rising streaming music services globally, provides various tiers: Amazon Music HD, Amazon Music Unlimited, Prime Music, and Amazon Music Free. For the songs on Prime Music & Music Unlimited, it offers a bit rate of 256kbps in encoded MP3 format, while Amazon Music HD & Ultra HD is in encoded FLAC format at 3730kbps (24-bit/192kHz) quality.
All these Amazon Music files are encrypted and cannot be exported to any media player, like JRiver. So you need to convert Amazon Music songs to above normal audio formats that JRiver supports, such as MP3 and FLAC.
