Górniak was also asked to sing the Polish national anthem at the 2002 FIFA World Cup in Busan, South Korea, which she did. However, her performance had a decidedly mixed reception, being sung at a much slower tempo than usual. In March 2003 international version of "Perła" was released, under the title "Invisible". A brand new club tune "Impossible" was the first international single from the album. Its mediocre success only in Germany, Austria and Switzerland made "Invisible" a commercial flop with over ten times worse international sales than her previous studio album. The Polish version called "Perła" went gold in her native country in a time of phonographic crisis, selling 40,000 units. A year later she was dropped from Virgin and after ten years of cooperation she also left her Polish label. In that time she had another hit in Poland, "Nie było" ("Never Been"), recorded with Polish metal band Sweet Noise.
