This is one of three new tracks included on Teenage Dream: The Complete Confection, the re-released version of Perry's third studio album. The Tricky Stewart-produced dance-pop song finds Perry all sexed up. "Tonight I'm gonna come alive/ Make you forget about your nine to five/ Are you ready for your blood to rise?/ Tonight's the night I'm dressin' up for you," she sings.
This was originally written for the 2010 Teenage Dream album but didn't make the cut. However Stewart told MTV News its appropriate for the Confection re-release. "It definitely fits," he said. "It's right there in what her sensibilities are as a musician and a songwriter. She doesn't change much. She has a very keen musical taste. It'll be really good."
