After winning the competition, Rúzsa’s album, featuring the songs she performed during the show’s finals, went triple platinum and to date has sold around 80,000 copies. Her first artist album Ördögi Angyal (Devilish Angel) was released on her birthday (November 28, 2006), and has sold 36,000 copies so far. These two records were the biggest-selling releases in 2006 in Hungary.
Rúzsa was voted New Talent of the Year in 2006, representing Hungary at the 2007 Eurovision Song Contest in Helsinki. She decided to sing in English because she felt that the lyrics of the song are of high importance and wanted people to understand what Unsubstantial Blues was all about. The semi-finals took place on May 10, 2007, and Rúzsa made her way to the finals in second place with 224 points. At the final on May 12, 2007, she finished ninth with 128 points. Being the songwriter of Unsubstantial Blues, she was also granted the Best Composer Award, which is given to the best songwriter among the Eurovision song composers every year.
