If you're a big pop culture fanatic, there's a decent chance you were watching the iHeartRadio Music Awards on Sunday night (March 5), when celebs like Thomas Rhett, Ed Sheeran and Bruno Mars took the stage. It was quite the party, with The Chainsmokers shouting out EDM, little kids pretending they were Coldplay and Katy Perry getting quinoa in her teeth (trust us, that was a whole thing). And there's no party without the biggest hits, which were served with superstar flair. Here are five iHeart performances that you need to watch again:

Bruno Mars

Katy Perry

Katy Perry has been touting her new single, "Chained to the Rhythm," all over the awards-show circuit, and her latest stop was at the iHeartRadio Music Awards. Sticking to her so-comfortable-we're-living-in-a-bubble theme, Perry took the stage in a hamster wheel, pacing a treadmill going nowhere. A giant, bulbous hamster bobbed around while a crew of kids with Communist-shaped hammers tinkered away obliviously. How's that for a statement?

Ed Sheeran

Ed Sheeran worked some his loop pedal magic to captivate the California crowd with one of his new singles, "Shape of You." Layering his own vocals and getting everyone to clap for an entire song (a true feat), Sheeran rocked through the accoustic jam with a bit of edge in his voice, a glimpse into the duality of grit and charm in his upcoming album.
