More content is now available for Amazon Prime ($99/yr.) members in the U.S.
Now, along with the Amazon Prime Video (streaming video) and the Kindle Owners’ Online Lending Library (KOLL) Prime members can access (at no additional charge) more than one million music tracks with new content being added regularly.
Prime members can choose exactly which songs and albums to listen to, or they can sit back and listen to hundreds of expert-programmed Prime Playlists [and can] also download songs from the Prime Music catalog to their mobile devices for offline playback on planes, trains and anywhere they’re without an internet connection.
Apple’s iTunes Radio and Pandora is available at no charge but users can’t listen to specific tracks. Ad-supported. Same for Songza.
A free ad-supported version of Spotify is available for desktop/laptop as well as tablet users.
