The pop star explains why her latest album won’t be on Apple’s new streaming service.

Add noted Spotify opponent Taylor Swift to the growing list of artists and entities that have taken issue with Apple Music’s royalty-free trial period. In an open letter on her Tumblr, Swift explains why 1989 won’t be available on Apple Music.

“I find it to be shocking, disappointing, and completely unlike this historically progressive and generous company,” she writes, explaining that it’s not about her, it’s about the new artists, young songwriters and producers who “will not get paid for a quarter” during the free trial period.

“These are not the complaints of a spoiled, petulant child. These are the echoed sentiments of every artist, writer and producer in my social circles who are afraid to speak up publicly because we admire and respect Apple so much. We simply do not respect this particular call,” she explains.

Noting that Apple working towards paid streaming is “beautiful progress,” she asks the company to reconsider the three-month trial period. “We don’t ask you for free iPhones. Please don’t ask us to provide you with our music for no compensation.”

Update: Apple has reversed its decision not to pay artists during the trial period following Taylor Swift’s open letter.
