Old ball romantic songs before 1950


I know old jazz and pop songs from 1920 till 1960 but it seems this ball room is like some kind another category? sometimes it feels old pop from 1930 can be similar but the rhythm of the ball room music is litle different;

I found for now these artists:

Al Bowlly and the Ray Noble Orchestra

Midnight The Stars And You - 1934

It’s All Forgotten Now 1934

Henry Hall and the Gleneagles Hotel Band
Home 1932


Im looking forward to this kind of music info, and tips! Is it call ball room music?

Thank you so much
