Whats a good modern song to sing in a talent show?

My friend and I want to sing a song in the talent show, we are in
Middle School. We want a pop or hip hop type song or like Taylor
Swift. Any type is fine as long as its not hardcore country or
anything. Can you give us some song names and maybe some tips? We are
in band so we are used to being on stage but we have never sung on one
before. Thanks :)
