In 2003, Martika and her husband, musician Michael Mozart, formed the band Oppera. Adopting a Latin pop sound, she and Mozart released Oppera's debut album "Violince", in 2004. Rapper Eminem used a sample of her biggest U.S. hit, "Toy Soldiers", for "Like Toy Soldiers", a track on his 2004 album "Encore" and featured Martika on the chorus of the track. In response, Martika's British greatest hits album was repackaged with its title altered to "Toy Soldiers: The Best of Martika". A biography was added to the album insert reflecting the new Eminem sample, though it asserted that she had not released any albums since "Martika's Kitchen".
