Songfacts®:

• Demi penned this synth anthem with Ryan Tedder and Noel Zancanella. The pair, who previously worked with the singer on her 2011 Unbroken track "Who's That Boy?" also produced the tune. Tedder revealed that the idea to produce the song was his own. He stated: "That record we did intentionally because I wanted to... I heard it on her demo-reel and the next day I woke up and the melody was in my head, and I couldn't get it out of my head for two days, that's when I knew."
• Speaking about Lovato's vocals on the song, Tedder told the UK station Capital FM: "She came in and just ripped it. She, in pop music has one of the biggest ranges, possibly the highest full voice singer I've ever worked with."
  
  "She can belt full voice like three octaves above middle C, it's just crazy," Tedder added, "and with complete power and complete control. At the beginning she's singing the lowest note she's ever done, and by the end she's going as high as she's ever gone."
• The song inspired the name of Lovato's Neon Lights Tour.
• The Ryan Pallotta-directed video finds Lovato taking a dip in a purple pool of water before she hits the dance floor at an underground rave. As she starts dancing along, the lights go out to show the singer literally glowing, thanks to some neon makeup.
