Making good on her promise later that evening, the 28-year-old pop star tweeted, "You want another shade of #PRISM? Let's take WALKING ON AIR to the TOP spot & in exchange, I'll play a NEW song you've never heard tonight!"
Speaking to Billboard about the track, Katy shared, "That song is evident of how tough it really was at a certain point. I asked myself, 'Do I want to endure? Should I continue living?'"
