Little did they know that the singer's rival, Taylor Swift, would swoop in at the last moment to steal Perry's thunder by releasing her entire back catalogue on streaming services that same night.
Taylor Swift has returned to Spotify and other streaming services. An Apple executive quickly responded to Swift's plea, and her music ― including her new album at the time, "1989" ― was made available for streaming.
Officials at the Recording Industry Association of America (RIAA) announced she had passed the mark on Thursday - the same day the singer learned her album 1989 had sold over 10 million copies globally.
In truth, her back catalog was available in piecemeal or in full on various services well before early this morning.
Pop vixen Perry recently addressed her long-term feud with Swift and confirmed that she was the subject of Swifty's catty hit song "Bad Blood".
Swift accused Spotify of devaluing artists by essentially giving music away for free, pointing to the platform's advertising-backed tier that gives access to non-subscribers.
What do you think of Swift's decision? The first one is more probable although you can't discount the other. And because of the legal structure of song licensing in the states, listeners on Pandora's radio service also could hear tracks from her catalog.
If that wasn't enough, in the shaky lead up to the release of Witness - which music publication Spin noted as a "spectacular failure" point in Katy's career - Perry has brought up the matter with Swift more times than Taylor even spoke on the song it's supposed based about itself. A few years ago, "1989" became one of the fastest-selling albums of the decade. Up until now, Apple Music has been the only place to listen to her music.
Artists who remain firm against streaming their music include English progressive rock pioneers King Crimson, US heartland rocker Bob Seger and experimental metal band Tool.
