Most of the music put out by Jews today is not real Jewish music – they’re trying to copy the sounds of non-Jewish music, with the loud, rocky sound. If you want that type of music, non-Jewish is better. They simply have better songs.
If, however, you’re looking for real Jewish music, nothing beats some of the older Jewish stuff out there. Listen to the early D’veykus albums, Regesh, the old Chassidic stuff like Modzitz, and you’ll see that nothing compares to it. They have songs that really touch the soul.
