Swift had previously debuted four singles from Reputation on Apple Music, including Look What You Made Me Do, ...Ready For It?, Gorgeous, and Call It What You Want, but she kept the full 15-track album off of Apple Music and other services for the past three weeks.
Besides the previously-released singles, there were a few behind-the-scenes videos about the making of Reputation's music videos that were exclusive to Apple Music released a few weeks ago. With the launch, all of this content will be streamable on Apple Music on December 1. In the United States, we can likely expect to see "Reputation" available on Apple Music starting at 12:00 a.m. Eastern Time.
UPDATE 📲 #reputation is NOW available for streaming on @Spotify in Australia and New Zealand and will be available in the US tonight at midnight (12am ET on December 1st) 🎶 https://t.co/MgKDbVdzwE pic.twitter.com/p8GGv7RpkY— Taylor Swift Updates (@SimplySFans) November 30, 2017
Swift and Apple have had a somewhat rocky relationship, with the artist in 2015 penning an open letter to Apple Music about the service's initial stance on refusing to pay royalties to artists during the three-month free trial period. Swift opposed this aspect of Apple Music, so she decided to keep her 2014 album "1989" off of Apple Music at the time.
Soon after the letter was publicized, Apple reversed course and began paying artists during this period of time when new subscribers are on the free trial of Apple Music. This eventually led to a closer relationship between Swift and Apple, with her music debuting on the service along with the launch of a series of Apple Music ads starring Swift that debuted throughout the spring of 2016.
