In a pop star gut punch heard 'round the world, Taylor Swift did her best to overshadow Katy Perry's release of Witness tonight. Swift decided that as Perry shared her new album on YouTube via a special event (Katy Perry: Witness World Wide), she'd release her entire back catalog on all streaming services.

According to the Taylor Nation Twitter, the gesture is "in celebration of 1989 selling over 10 Million Albums Worldwide and the RIAA's 100 Million Song Certification announcement."
