Sony's Music Unlimited streaming service is being updated today to offer high-quality 320 kbps AAC music on all platforms, including Android. The service, which offers unlimited (go figure) music streaming for the monthly price of $9.99, is hoping to persuade users to try it over competing services like Spotify and Rdio. 320 kbps AAC is generally regarded as a high enough quality streaming that general users won't notice the difference between it and locally stored files, but also keeps data usage from streaming reasonably low.
You can download the Music Unlimited app from the Play Store link above, and there is currently a 14 day free trial available when you sign up. The higher quality audio may be enough to have more users trying this service going forward.
