Hungary participated in the Eurovision Song Contest 2007 with the song "Unsubstantial Blues" written by Magdi Rúzsa and Imre Mózsik. The song was performed by Magdi Rúzsa, who was selected to represent Hungary at the 2007 contest in Helsinki, Finland through the "Discovery of the Year" category of the 2007 Fonogram Hungarian Music Awards, organised by the Hungarian public broadcaster Magyar Televízió (MTV). In December 2006, MTV announced that they would be returning to the Eurovision Song Contest after a one-year absence following their withdrawal in 2006 due to financial reasons. Six artists competed in the "Discovery of the Year" category of the awards and Magdi Rúzsa was selected as the winner based entirely on a public televote. The Hungarian song, "Unsubstantial Blues", was internally selected and announced on 12 March 2007.

The Eurovision Song Contest 2007 was the 52nd edition of the Eurovision Song Contest. It took place in Helsinki, Finland, following the country's victory at the 2006 contest with the song "Hard Rock Hallelujah" by Lordi. Organised by the European Broadcasting Union (EBU) and host broadcaster Yleisradio (YLE), the contest was held at the Hartwall Areena, and consisted of a semi-final on 10 May, and a final on 12 May 2007. The two live shows were presented by Finnish television presenter Jaana Pelkonen and musician and TV-host Mikko Leppilampi. In addition, Krisse Salminen acted as guest host in the green room, and reported from the crowds at the Senate Square.
