It's a battle of the best karaoke pop songs! Picture it: You're out on a night on the town with your friends, and someone inevitably decides to hit up some good, old-fashioned karaoke. Would you go for a classic, like Prince's 'Kiss'? How about a '90s-era smash like Backstreet Boys' 'I Want It That Way' or 'Baby One More Time' by Britney Spears? Or maybe Justin Bieber's 'Baby' or Katy Perry's anthemic 'Firework' is more your speed. But of course, you can't forget modern pop staples like Miley Cyrus' 'Wrecking Ball' and Lorde's 'Royals'... decisions, decisions! Which song would you rather sing at karaoke?
