There is no way whoever wrote this song ever had playradioplay in their head at all. I'd be shocked if the song writers knew who playradioplay is. You be the prince and ill be the princess isnt some lyric given to taylor from God or something, sounds like something any high school artist could think of.
just a similar lyric, said in a similar way.
playradioplay was signed to island, and released his song before taylors was recorded, i believe.
