"Alt Dudak", written and composed by Altan Çetin, was released as the album's lead single. The track list for Mükemmel was released on 7 May by Hande Yener on her Twitter account. The release date, however, was postponed a number of times. It was first reported that it would be released on 3 March, and later this date was changed to 13 May and 20 May. Following the Soma mine disaster, the release date was further postponed to 2 June. Recordings for the album took place at Kaya Müzik Studio, Marşandiz and Volga Tamöz's Studio. Hande Yener's eleventh studio album, Mükemmel, was released on 2 June 2014 by Poll Production. It ranked third on D&R's Best-Selling list and following its release on iTunes, it was downloaded over 7,000 times in a few hours. By the end of the year, it sold 50,000 copies in Turkey, becoming the seventh best-selling album in 2014. Music and visuals Mükemmel is a pop album with elements of electronic music. In Yener's words "It's a complete mix. It contains both Hande Yener's romantic songs, and songs that resemble my old works. The songs that have an electronic effect are a lot of fun. I just wanted an album to impress everyone. I didn't want it to have one style. We included songs with elements of rock and roll, R&B, reggae." As they did not want to choose between the songs that had already been prepared for the album, the company released all of the pieces in a two-disc edition. The album contains fourteen songs, two covers and six remixes. Five remixes were prepared for the song "Alt Dudak", which is the opening piece in both of the discs and was described by Sadi Tirak as an "awesome hit". The song "Herkes Yoluna" is one of the songs on the first disc and was described by Yavuz Hakan Tok as the "album's most powerful hit". "Unutanlar Gibi" was released as a duet between Yener and Mehmet Erdem. Out of the album's two cover songs, the first one was included in the album's first disc, and was a cover of Sezen Aksu's song "Kış Masalı" from her album Sezen Aksu Söylüyor (1989) (Its name was changed to "Bir Kış Masalı" in the album). The second cover, "Bir Köşede Yalnız", was included in the second disc and was originally performed by Ajda Pekkan for her album Süper Star
