This is the last thing Perry needs as she launches her new album to an inarguably lukewarm reception.
She's clearly now come to terms with the new music landscape and has reconciled her differences with Spotify. Spotify said in a statement: "We can confirm that Taylor Swift's entire back catalogue is now available on Spotify for her millions of fans to enjoy".
Swift got into a very public spat with Spotify in 2014 after she removed her entire catalog from the streaming service, including 1989. Another said: "I aspire to be as petty as taylor swift releasing her discography for streaming the weekend katy perry's album drops", and one other weighed in: "This is way more than just a beef. this is sabotage".More news: US official makes brief appearance at G7 environment summit
Although the singer admits that publicly feuding with Swift, 27, impacts her image with fans, Perry added, "I mean, I'm not Buddha". In 2015, she criticized Apple Music for not paying artists for songs streamed during a customer's three-month trial.
In a recent interview, the 32-year-old songstress cursed Swift's popular single "Bad blood", which was reportedly about the duo's prolonged dispute.
