Hi Revooh16
I was also in your position once a long time ago. I switched from the worst rap to L’Chaim Tish. My advice to you is not to let yourself become crazy over it. Find Jewish music that you enjoy (even only a little) and start with filling your music time with that. It will be very hard in the beginning because you will get these strong urges to switch back to non-Jewish music. But those urges are normal and OK, don’t let them take you over, just accept them (not give in to them) calmly and let them pass. Tell yourself to calm down, relax “its ok, I don’t have to give in to it. This feeling will pass and I’ll be fine”. Eventually, your tastes will change over time and you will come to appreciate Jewish music and the way it elevates you much much more.
