In the final week of April 2012, the Top 10 of the Billboard Hot 100 was a hotspot for pop. The Wanted and One Direction’s s respective singles “Glad You Came” and “What Makes You Beautiful” were in the midst of a battle of the boybands. Nicki Minajsaw success in the pure pop of “Starships” and Carly Rae Jepsen’s earworm “Call Me Maybe” was soon to be entirely inescapable. The other slots were occupied by Kelly Clarkson, Katy Perry, Justin Bieber, Fun. and Flo Rida, and then there was Belgian-born alternative artist Gotye sitting at No. 1 with the slow-burning breakup record “Somebody That I Used To Know.”
