There's some bad blood brewing between Taylor Swift and Apple Music.

The pop superstar penned an open letter to Apple explaining why she won't allow her new album, 1989, to stream on Apple Music. Apple is offering a free three-month trial to users who sign up for the new service, but is also refusing to pay any royalties to songwriters, producers or performers during that time period.

"I find it to be shocking, disappointing, and completely unlike this historically progressive and generous company," Swift wrote. "It is unfair to ask anyone to work for nothing."

"This is not about me," she continued. "Thankfully I am on my fifth album and can support myself, my band, crew, and entire management team by playing live shows. This is about the new artist or band that has just released their first single and will not be paid for its success. This is about the young songwriter who just got his or her first cut and thought that the royalties from that would get them out of debt. This is about the producer who works tirelessly to innovate and create, just like the innovators and creators at Apple are pioneering in their field...but will not get paid for a quarter of a year's worth of plays on his or her songs."

It's a bold move for Swift, who relies primarily on iTunes to distribute her music after she previously pulled all of her music from the streaming service Spotify, citing similar reasons. "Apple has been and will continue to be one of my best partners in selling music and creating ways for me to connect with my fans," Swift acknowledged. "I say this with love, reverence, and admiration for everything else Apple has done. ... We don't ask you for free iPhones. Please don't ask us to provide you with our music for no compensation."
