In late 1920s Daniłowski spent two years working for the Polish embassy in Paris, where he fell in love with jazz and tango, two styles of music gaining increasing popularity in Europe at that time.
His songs were sung by many of the most notable vocalists of the epoch, including Adam Aston, Mieczysław Fogg, Zofia Terné and Mira Zimińska-Sygietyńska, to name but a few.
He later wrote scores for numerous other films, including Dziesięciu z Pawiaka (1931), Dvanáct křesel (1933), Wacuś (1935) and Dodek na froncie (1936).
The lyrics for his songs were written by some of the most renowned Polish authors of the time, including Julian Tuwim, Marian Hemar, Konrad Tom and Jerzy Jurandot.
In hid capacity of record company executive, promoter, and publisher, he was largely responsible for the "big-band" sound of polka music that became pre-eminent in the America.
