This song features Justin Bieber. Songz told MTV News that it says a lot to have a star of the Canadian Pop star's caliber dip into the R&B world. "I'm elated for people to hear how [Bieber] sounds on it, because the first reaction I get from a lot of people is: 'Who is that?' Because you don't expect him to be on a record like that," he told MTV News.
"It's incredible. We've seen Justin Bieber grow in the last few years. People have a lot of opinions on how he's chosen to live his life in a lot of ways, but one thing we can't deny is that musically, he's evolved," Songz added. "Last year he went out on an edge and made the world – basically - accept him doing R&B."
ABBA's Bjorn Ulvaeus and Benny Andersson conceived "Dancing Queen" as a dance song with the working title "Boogaloo," drawing inspiration from the 1974 George McCrae disco hit "Rock Your Baby." Their manager Stig Anderson came up with the title "Dancing Queen."
