AOK (album)
 AOK is a studio album by the Polish singer and dancer Mandaryna released in 2009. Musically the album references works of artists such as Lady Gaga. The album was expected to be a big comeback for the singer after her 2005 Mandarynkowy sen album and legal problems in the following years but turned out a commercial failure. AOK did not chart and only 5000 copies were sold at all.
