Users of Sony’s Music Unlimited cloud/streaming music service are getting a bump in audio quality, with streams now available in 320 kbps AAC through a new “high quality streaming” option. Well, users of certain devices are getting it: those on PC/Mac, Sony’s own Android smartphones and tablets, and the PS3. Those on other companies’ Android devices or iOS will have to wait until “later this year” to get the quality boost, for unexplained – and frankly puzzling – reasons. It’s the latest example of a music service offering 320 kbps streams as an option, with Spotify, Deezer, MOG and Google’s cloud service all at that level. So this is more Sony catching up with competitors rather than forging ahead.
