T-Mobile is adding six new music services to its "Music Freedom" program, allowing you to stream music from them at 4G LTE speeds without it counting against your monthly LTE data limits. Songza, Rdio, AccuRadio, Black Planet, Grooveshark, and Radio Paradise are now members of the program.
The notable exception is Google Play Music, which was the most-requested choice among T-Mobile subscribers in a recent social poll.
CEO John Legere took to Twitter to reassure customers that Google's music service would soon join others on the magenta network.
T-Mobile did not specify when this would happen, only saying Play Music is coming "later this year" on its official blog. It is unclear what is causing the holdup, whether it be technical work needed on the T-Mobile network or tied to a potential Google Play Music/YouTube streaming service revamp.
Google also recently announced it was acquiring Songza, but has not revealed any plans to shut the service down.
The newest streaming services join Spotify, iHeartRadio, Pandora, iTunes Radio, Rhapsody, Samsung Milk Music, and Slacker Radio as sanctioned T-Mobile Music Freedom members.
The additions are only the latest volley in T-Mobile's efforts to differentiate itself as the "uncarrier." This has played out most recently in price wars with Sprint, with each seeking to one-up the other through promotions and discounted packages (though not all of them are are good deals).
CEO Legere has also been waging his own battles on Twitter, proclaiming T-Mobile will surpass Sprint as the nation's third-largest carrier, appending many of his tweets with #overtakesprint.
