Prince William and Kate Middleton, the Duke and Duchess of Cambridge, may be pretty darn formal while out in public on official royal biz. But most folks know by now that behind closed doors, these two are just like any other couple (besides the fact that, ya know, they live in a castle). That鈥檚 why despite having one of the most ornate weddings of our lifetime, they also happened to have a super fun playlist to make sure their celebration was the party of a lifetime.

Prince William and Kate Middleton wedding

With strict pseudo-rules dictating how the couple acts in public, fans of the royal family witnessed plenty of traditions when William married his love back in 2011. But when the cameras stopped rolling and the guests started partying, the newly married duo popped on a playlist that had nothing to do with etiquette and everything to do with having fun!

Check out a few of the songs on Prince William and Kate Middleton鈥檚 wedding playlist below.

1. 鈥淵our Song鈥 鈥 Ellie Goulding: The singer performed Elton John鈥檚 鈥淵our Song鈥 for the couple鈥檚 first dance, telling Vanity Fair, 鈥淚 did their first dance and like, talk about scary. I was so nervous, my hands were shaking.鈥

2. 鈥淢r. Brightside鈥 鈥 The Killers: Ellie Goulding and her band also performed a cover of The Killers鈥 鈥淢r. Brightside鈥 for the new royal couple.

3. 鈥淪tarry Eyed鈥 鈥 Ellie Goulding: Apparently one of William and Kate鈥檚 favorites, Ellie Goulding was sure to also slip 鈥淪tarry Eyed鈥 into her set.

4. 鈥淪uperstition鈥 鈥 Stevie Wonder: Not one we would have guessed, but the addition of Stevie Wonder鈥檚 鈥淪uperstition鈥 is awesome all the same.

5. 鈥淵ou鈥檙e the One That I Want鈥 鈥 John Travolta and Olivia Newton-John: Okay, now this is just an absolutely adorable choice. We really wish we could鈥檝e seen the newly married couple grooving to this tune. According to Pop Sugar, a guest told the Mirror UK, 鈥淭he Grease number brought the house down. [Prince William and Kate Middleton] stood holding hands in the middle of the dance floor grinning, then suddenly the opening bars of the song came booming out鈥 Will and Kate began dancing around, pointing at each other and mouthing the words. It was hilarious.鈥

6. 鈥淪ex on Fire鈥 鈥 Kings of Leon: For the last song of the night, a DJ set a sizzling tone by playing Kings of Leon鈥檚 鈥淪ex on Fire.鈥 Oh my!

With the couple set to celebrate their sixth wedding anniversary on April 29, we have to wonder if any of these songs will be playing in the background.
