All good things must come to an end. So it is with PopCrush's annual Prom King and Queen of 2015 poll -- the final round is upon us, which means we're mere weeks away from crowning either Taylor Swift or Ariana Grande with the highly coveted title of PopCrush Prom Queen. If either of them ever needs to produce a resume, this honor will definitely be listed beneath "achievements." Now it's up to you guys to ensure that your fave wins.

Taylor Swift has successfully spun herself a brand new image that's so far removed from the lovelorn country-pop starlet she started out as. When she first emerged onto the scene with her forced country-twang (you're from Pennsylvania, Taylor), she came armed with a back catalog of songs about unrequited love, puppy love and lost love. She quickly became the unofficial breakup representative for sad sacks everywhere, and if you've never cried to a Taylor Swift song on the subway, you're probably lying. With each album, she leaned a little more pop and a little less of the angst, until she released the critical darling 1989 (really, even Dave Grohl loves her), somehow never sacrificing her artistic integrity to make a buck -- yet still making more money than most of us will ever see in our lifetimes, anyway.

Ariana Grande is a pint-sized powerhouse who also managed to reinvent herself, albeit in a different way. She made the transition from television star to pop star, effectively erasing all ties to her Nickelodeon past -- not as easy feat for someone who got her big break via a massively successful television show. But she went on to collaborate with huge artists like Nicki Minaj, Jessie J and Iggy Azalea which resulted in the release of some seriously catchy pop songs with major radio play.

The time is now -- you can vote for either Taylor Swift or Ariana Grande, once per hour, in the poll below. Be sure to get all your votes in before the poll closes on June 9 at 3PM ET, or you'll have no one to blame but yourself.
