US mobile operator T-Mobile launched its Music Freedom initiative earlier this year, promising that usage of Spotify, Pandora, Rhapsody, iHeartRadio, iTunes Radio, Slacker and Samsung’s Milk wouldn’t be counted towards customers’ 4G data caps. Now it has added more services in response to customer feedback, but see if you can spot the one that’ll cause controversy: AccuRadio, Black Planet, Grooveshark, Radio Paradise, Rdio and Songza. Yes: Grooveshark, the service infamous for having large amounts of unlicensed songs, and resulting lawsuits from major labels alleging that the company’s own employees were actively uploading copyrighted songs to get around takedowns. Critics will be sure to complain at the sight of the service getting a new veneer of respectability from its inclusion in the Music Freedom program. Meanwhile, T-Mobile says it will add Google Play Music to the initiative later this year, claiming that already its customers are streaming 5m more songs per day than before its launch.
