In a surprise announcement, T-Mobile just announced that you will be able to stream music for free (as in it won't count against your data limit) from most of the major music services. This includes Spotify, Pandora, Slacker, Rhapsody, iHeartRadio, and iTunes Radio, plus Samsung's Milk and Beatport when it launches.
Not only will music not count against your data bucket, but it will continue to stream at high speed and full quality if you've already reached your data limit. This is absolutely fantastic. Basically every time I've gone over my data limit it's been because I was streaming music too much. Having to never worry about that is a big deal.
T-Mobile is pledging to expand Music Freedom. Soon you'll be able to go to T-Mobile.com/musicfreedom (not yet live) and vote for your favorite streaming service, and the most popular ones will be added to the program. This is a good thing because there are still some major omissions, Rdio and Google Play Music being the biggest that jump to mind (can we get those voted in, like, now please?).
T-Mobile is also announcing a new streaming service called Rhapsody unRadio. For people on T-Mobile's (newer) LTE plans the service will be entirely free. For non-unlimited customers, it'll be $4 a month. Not too bad.
So, obviously, this is pretty great. Here's hoping the other carriers follow suit. Music Freedom rolled out today, so crank up your speakers. [T-Mobile]
