The single was written and produced by Max Martin (Taio Cruz, Katy Perry), who also worked with the 17-year-old singer on her 2010 album, 'Sparks Fly.'
'Dancing Crazy' is the epitome of pop, appealing to listeners with its young, carefree chorus: "Everybody's dancing, dancing crazy and we never stop / We never stop / Everybody's raging, raging crazy / Put your hands up / Put your hands up."
The song also features a section in which Cosgrove tips her hat to the vocal style of Kesha. "I like you and you like me," she says. "We get together and we're happy. Did you hear me say that? Did you hear me say that?"
Cosgrove will begin her 22-date Dancing Crazy tour on Jan. 24. Get a full list of show dates on TourTracker, and listen to 'Dancing Crazy' on AOL Radio's Fresh 40 station now.
