"Jews did not create the popular song; they debased it. The time of the entry of Jews into control of the popular song is the exact time when the morality of popular songs began to decline. The "popular" song, before it became a Jewish industry, was really popular. The people sang it and had no reason to conceal it. The popular song today is often so questionable a composition that performers with vestige of decency must appraise their audience before they sing."
