Well I think music is music but there is something in kabbalah (which I was told so not sure how reliable this is…) that you are connected to the neshama of the person who’s singing the music.
Now i’m not sure if its the singer, the origional composer or the musician that its referring to.
And actually because of all these things I actually create my own tunes up, and so many times friends have asked me to sing a song thats non jewish and make it jewish which I completely REFUSE to do. I BH know how to make up my own tunes… I don’t understand why other singers don’t do the same.. we want to hear NEW stuff anyways!! Not the copy of the non jewish……
