The albums will become available today, Swift's management said on Twitter. One tweeted: "I aspire to be as petty as taylor swift releasing her discography for streaming the weekend katy perry's album drops".
Taylor Swift has released her entire music catalogue on streaming services to celebrate her latest album, 1989, selling over 10 million copies worldwide.
The timing was even more interesting since the "Dark Horse" songstress, 32, has publicly discussed her feud with Swift multiple times in the last few weeks while promoting her fifth record.
"It's my opinion that music should not be free, and my prediction is that individual artists and their labels will someday decide what an album's price point is", she continued.
Taylor Swift's five audio albums have not been available for online streaming on platforms such as Amazon Music, Spotify, and Pandora since 2014.
Once friends, the pop divas have been embroiled in a feud that supposedly inspired Swift to write her hit "Bad Blood" about Perry, who then supposedly retaliated with her song "Swish Swish".
"There's a situation. Honestly, it's really like. she started it and it's time for her to finish it", she said on the "Late Late Show with James Corden" at the end of May.
