"After the events of this week, I've decided to put 1989 on Apple Music...and happily so," the "Bad Blood" singer tweeted on Thursday.
In an open letter on Sunday, Swift slammed Apple over its decision not to compensate artists during Apple Music's three-month free trial, calling it "shocking" and "disappointing."
Apple made a U-turn in its policy shortly after Swift released the letter and said it planned to pay artists royalties during the trial period.
The news comes just days before the June 30 launch of Apple's new music-streaming service.
Eddy Cue, senior vice president of Internet services at Apple, quoted Swift's tweet in a response on Twitter, saying "See you on #AppleMusic on June 30!"
