With increased exposure in Croatia, Kaliopi signed a record deal with Aquarius Records and released her first single, "Probudi me", in Croatia in 2007. The release was followed by a compilation album, "The Best of", which was also released in Croatia. In May 2007, Kaliopi released the single "Grev", which she composed as the theme for the film "Elegija za tebe". In November 2007, Kaliopi was a judge and a guest performer at the Albanian music event Kënga Magjike. She received critical praise for her performance of "Ako denot mi e nokj", which she dedicated to the late Toše Proeski, who had been involved in a tragic accident just a month earlier.
