Amazon has been exploring changes to its Prime subscription service, and while drone air delivery may be years out, a music streaming service is a realistic possibility. The company already offers video streaming via its Prime service in the form of a limited selection of its total Instant Video library that can be streamed for free with a yearly Prime subscription. on the music side of things specifically, Amazon already has a massive downloadable paid-for MP3 library with a browser-based (and a new PC application) digital locker and media player.
Amazon Cloud Player, a browser-based media player for purchased MP3 files.
In short, all of the pieces for a music streaming service are in place. Amazon has the e-commerce and programing experience, distribution medium, and gobs of cloud storage and processing power. Amazon simply needs the go-ahead from the labels in the form of licensing agreements which appear to be in progress according to Recode.
An Amazon-run music streaming service would face stiff competition from existing competitors such as Spotify, but if any company can come in and make it work at scale in a competitive market it is Amazon. Especially if Amazon is able to replicate music streaming and offline caching using mobile apps like Spotify offers without charging extra for the privilege. Music streaming seems to be a natural addition to its Prime Instant offering, and may just be the spoonful of sugar that makes a possible Prime subscription price increase easier to swallow.
