Amazon is planning two music subscription services, according to rumors that began circulating last week. One is a $10 a month offering that is similar to Spotify and Apple Music, and the other is a $4-$5 a month cut-rate service available only on Amazon's Echo device. Amazon reportedly wants to launch both in September, but it has yet to finalize deals with major music labels and publishers, or to settle on pricing for the Echo-only service, which will be ad-free and offer unlimited music on demand.
