During his set, the singer delivered "Talk Dirty," "Cheyenne," "Wiggle" and an extended jam on the massive smash "Want to Want Me," which recently became the most-added track in the history of top 40 radio.

Derulo told Billboard that his music is a reflection of his daily life. "I write songs based on things that I go through, things that I'm dealing with, things that are happening in my life," he explained, noting that "Want to Want Me" is based on a true story.

"If a song is singing your life you feel like that song was made for you," he continued. "I go through that all the time with being a fan of music."

Derulo also pointed out that the summer festival season is his favorite time of the year. "You get all these party crowds and that's kind of my life right now," he said. "I'm in this party mode and just trying to live and have a good time. Life is so short."
