Amazon undercuts Spotify and Apple Music with 7.99 streaming for Prime members

Amazon is introducing its answer to Spotify and Apple Music, and it's playing to win. Amazon on Wednesday launched Amazon Music Unlimited, its on-demand streaming service. The new offering is priced aggressively, with Amazon Prime members able to subscribe to the service for 7.99 a month -- below the 9.99 rate popularized by Spotify, Apple Music and just about every other major music streaming option. The on-demand streaming service will work online and through a redesigned Amazon Music app as well as through the Amazon Echo. A separate for-Echo-only streaming plan will cost 3.99 a month.
