Reply To: Jewish music? Mah zeh?

You cannot call them parodies (unless it’s Gershon Veroba, whose parodic songs have a point to them) since a parody is making fun of something. These singers have heard a song, used the tune and put in their own words. It’s not necessarily gneivas mamon, it’s more like gneivas daas, since the original music was someone else’s idea.
