Amazon is getting into the streaming music game. The company has officially launched Prime Music, a new service that offers Prime customers access to over 1 million songs and hundreds of curated playlists. Right now those include things like expedited shipping from Amazon, on-demand movies / TV shows via Prime Instant Video, and Kindle ebook lending. Like Instant Video before it, Prime Music is Amazons latest attempt to shake up an industry with entrenched competition.
