Input: Question: How old was the singer who recorded "Midnight Sun" when it premiered? Passage:"Midnight Sun" is a song recorded by the Romanian female singer Elena Gheorghe. The song was recorded in summer 2010 and premiered on November 15, 2010, on Gheorghe's official YouTube channel. It was released under Cat Music exclusively in Romania. The song has more house influences than the previous number-one hit "Disco Romancing". It was sent to the mainstream radio stations in late November and it is promoted as the second single taken from Gheorghe's album entitled Disco Romancing. Lyrically, the song describes the shiver a millionaire wannabe guy gets when he sees Elena dancing. The song had its official radio premiere on the Romanian National Day, at radio ZU, though it premiered on Kiss FM a week earlier. Elena performed "Midnight Sun" live, on December 31, during a New Year special show, held by Pro TV. The music video was already shot in Bucharest and it was released via YouTube on May 13, 2011. The video features many special effects as well as the track listing for Gheorghe's upcoming album. The song peaked at number-one the Radio Top 50 and charted within the top ten in two other Romanian charts. In the official Romanian Top 100 it peaked at number-ten, thus making it Elena's fifth song to enter the top ten in Romania, after "Soarele meu", "Vocea ta", "The Balkan Girls" and "Disco Romancing". The song was performed at many dates throughout Romania.
