T-Mobile has added ay Music, Soundcloud, Xbox Music among 14 new music streaming services that work with T-Mobile’s Music Freedom plan. For users with an eligible phone plan, any music streamed from a supported service won’t count toward their data cap. Spotify, Rdio, ra, several other streaming apps are already on board. In August, T-Mobile said it was working to add ay Music, as it topped a subscriber poll of most-wanted services. The network says it doesn’t charge providers to participate in Music Freedom, so T-Mobile likely delayed the rollout until it had built enough capacity to accommodate its subscribers’ jam sessions. Head to the T-Mobile news release to see the full list of newly added services. T-Mobile says since launching Music Freedom this summer, subscribers are streaming an average of 66 million songs per day, using 200 terabytes of data. The impact on you: The more streaming services sign on to T-Mobile’s Music Freedom plan, the less you have to worry that rocking out to a long playlist will blow past your data cap. T-Mobile’s network still doesn’t have the same footprint as rivals Verizon AT&T, but fun plans like Music Freedom give you another reason to check it out.
