Most of the stuff put out now isn’t Jewish music. It’s music that happens to have Jewish lyrics to them.
Real Jewish music has the power to touch your soul. Listen to old Chassidic tunes (Modzitz is fantastic), listen to early D’veykus, Regesh, and other old-time Jewish singers/composers. The stuff just gives you a feeling when you listen to it, a feeling which can’t be described.
Most of the stuff that comes out now is popular when it comes out, and a few years later it’s gone. Nobody sings it anymore, people don’t really remember it. Real Jewish music lasts a long time. People still sing the classics, whether it’s Shalom Aleichem from Regesh 3, V’LeYerushalayim from D’veykus, or all the beautiful Shabbos niggunim from Modzitz. That is real Jewish music.
