"Kraina Lodu" is the Polish title of Disney's animated hit "Frozen," and "Mam tę moc" is the Polish version of its most famous song, "Let It Go." In the film it is performed by Queen Elsa as she finally stops hiding her ice powers and embraces who she truly is.
The Polish singing voice of Elsa belongs to Katarzyna Łaska, an actress and vocalist from Poland who is well known for her work in musical theater and film dubbing. She also sang "Pokaż się" in "Frozen 2." The Polish soundtrack of "Frozen" was a huge success and reached diamond status, helping make "Mam tę moc" a beloved anthem for a whole generation of Polish children and adults alike.
