I am not suggesting that song writers be destitute. I am suggesting that if money is the only factor motivating the writing of a song, it's unlikely that any particular ruach hakodesh is going to come down to you in the process.
I think he makes a very valid point there is only one problem.. There is no more ruach hakodesh.
The last person documented with ruach hakodesh was the Premishlaner ( I can see an argument brewing here). I will settle for Siyatah D'shmaya. I don't necessarily believe that all song writers currently in Jewish Music only write for the purposes of making money. Perhaps the reason those songs aren't any good is a lack of creativity and talent. The argument lives on.......
