From T-Mobile:

Today, T-Mobile announced it will be working with Grammy award-winning artist Zedd as he launches his new album, True Colors, and goes on tour later this year. To kick it all off, T-Mobile and Zedd are offering fans 250,000 free downloads of Zedd's new remix of his No. 1 hit single with Selena Gomez 'I Want You to Know.' The free downloads will go to fans who follow T-Mobile's Facebook and Twitter on the morning of April 8th. Zedd's fans are a mobile-first, data-hungry generation and are a natural fit for T-Mobile.

Also as part of today's announcement, T-Mobile announced that it is returning as the sponsor of the live stream of the upcoming Coachella music festival, in addition to being a charter partner for popular EDM site Beatport, which recently launched an iOS app that also counts itself as part of the un-carrier's Music Freedom program.
