Grooveshark, Rdio, Google Play Music, and four other music services will no longer count against data caps on certain T-Mobile US plans. In all, 14 streaming services will be exempt from LTE data caps by the end of the year as part of T-Mobile's "Music Freedom" program.

AccuRadio, Black Planet, Grooveshark, Radio Paradise, Rdio, and Songza should immediately become exempt. Google will be added "later this year," T-Mobile announced today.

"The new services join iHeartRadio, iTunesRadio, Pandora, Rhapsody, Samsung Milk, Slacker and Spotify already included in Music Freedom," the announcement said. "T-Mobile has a vision to add every possible music streaming service to Music Freedom, and any music streaming provider can be part of Music Freedom by applying through T-Mobile’s open submission process."

T-Mobile asked people to vote on which music services they want and Google was the most requested service.

Not all T-Mobile users will be able to use music streaming without eating up their data buckets, though. The feature is available only for Simple Choice plans. These are the plans where data is technically unlimited but gets throttled after users go through their allotments of high-speed LTE data. The music services won't count against LTE data limits.

Music Freedom is not available on T-Mobile's cheaper "Simple Starter" plans, which cut users off entirely after data caps are reached instead of merely slowing them down.

Unlike AT&T, T-Mobile is not charging companies to become exempt from data caps, but the company has still been criticized by net neutrality advocates for "choosing winners and losers online" and using data caps to push consumers onto certain favored services.
