Just in case anyone forgot that Taylor Swift is and probably always will be the #1 pop star, she's reminded everyone, including Katy Perry, of just how successful an artist she is.
In celebration of '1989' of selling over 10 Million Albums Worldwide and the RIAA's 100 Million Song Certification, she has brought her entire catalog back to all streaming platforms, after the very public pulling of the catalog back in 2014.
On the day that 'Witness,' Katy Perry's long awaited new album gets dropped.
Obviously 'Bad Blood' is still relevant, in many different ways.
Your move, Katy.
