Ania rose to stardom in 2004 with the release of Samotność po zmierzchu which was met with positive critical and commercial reception.

In the same year, she collaborated with Polish singer Krzysztof Krawczyk on his hit album ...bo marzę i śnię.

In February 2004, Dąbrowska released her debut album, Samotność po zmierzchu, which was a blend of pop, soul and jazz.

In the fall 2004, Samotność po zmierzchu achieved Gold certification in Poland[6] for the overall sales exceeding 40,000 copies.

Having contributed vocals and written songs for such artists as Maryla Rodowicz and Monika Brodka, Dąbrowska released her second album Kilka historii na ten sam temat in autumn 2006.

"Nigdy więcej nie tańcz ze mną" was chosen as the first single, with the music video directed by Dąbrowska herself, and enjoyed considerable success in Poland.

In 2009, Ania collaborated with a French band Nouvelle Vague and contributed vocals for their cover of Robert Palmer's classic song "Johnny and Mary".

The promotional Ania Movie tour was postponed due to a number of reasons, including pregnancy and health problems,[11] but eventually turned out a great success later in 2010.
