Katy Perry: Taylor Swift is trying to 'assassinate my character'

Some tweeters were upset that Swift's re-released music was stealing Perry's thunder. Fast forward to today, and it seems like Spotify and other music streaming services are here to stay. Perry and Swift have a long-running feud that dates back years to an incident where Perry thinks Swift mistreated a few backup dancers who previously worked for one of Perry's tours.

The singer removed all her music from streaming and made an announcement in 2014 when she condemned streaming services for not properly paying artists.

Swift, however, might want to end the dispute according to a Swift insider who told Us: "She honestly wants no part of this". Sure enough, all her albums were available at midnight on Spotify, Pandora, Amazon Music, etc.

A couple of years ago, the Grammy victor shook the music industry when she penned an open letter to Apple Music as she slammed their decision to not offer artist compensations during the free trial of the service. "ALL SHADE (sic)", a user contributed, and another added, "Taylor Swift putting her entire discography on Spotify the same night Katy Perry drops a new album is next level pettiness & I am all for it".

Perry's new album includes the song "Swish Swish", which is widely understood to be a diss track against Swift. The country-turned-pop superstar is offering her entire back catalog for streaming through all digital services.

"There's a situation", Perry told "Late Late Show" host James Corden last month while appearing with him on "Carpool Karaoke".

"Music is art, and art is important and rare", Swift wrote in an essay for The Wall Street Journal.

The pop star's management said the latest decision to return to all streaming services was taken to celebrate her album "1989" selling over 10 million copies worldwide. Valuable things should be paid for.
