Taylor Swift, apart from sharing a name with Apple’s new programming language, is becoming one of the firm’s biggest partners in the music world after initially getting off to a rocky start when the artist penned an open letter to Apple asking it to pay musicians for their work during Apple Music’s 90-day free trial. Ever since Apple reversed its stance and did exactly that, the pair have been best buds.

Taylor Swift’s 1989 World Tour Documentary video will be available exclusively on Apple Music starting December 20th. Here are the details.

The senior vice president of Apple’s Internet Software and Services Eddy Cue took to Twitter today to confirm in a series of tweets that Apple will now pay artists during three month free trial period of Apple Music in a complete reverse from company’s original policy.

Apple’s big new music venture goes live on June 30th with the release of iOS 8.4. Apple Music is set to allow its users to stream unlimited amounts of music to their iPhones, iPads and Macs without having to hand over a dollar beyond the $9.99 monthly subscription fee. It’s a model that’s not exactly new to the music industry, with Spotify, Rdio and others already doing that exact same thing. The music makers aren’t particularly happy with the deals they have with such companies, but surely things will be different with Apple, right?
