His album To co w życiu ważne reached number one on the Polish Music Charts.

Disco polo is a genre of popular dance music, created in Poland in the 1980s. It was initially known as sidewalk music or backyard music. This genre, a type of Polish urban folk music, had great popularity in the 1990s, peaking in 1995–1997, then gradually declining in popularity through the early 21st century. The genre then had a resurgence in the winter of 2007. The Polish PWN dictionary defines the genre as a Polish variant of disco music, with simple melodies and often ribald lyrics.
