Joe, you say the difference does 'make' a difference..but who to? I personally believe that Jesus will be as accepting of praise from any scource and in whatever form. There is nothing in scripture that suggests He prefers a certain kind of song/hymn.... I think we should just leave it to Him... I am sure He will be happy with it all.. where we as humans/the flesh/ the sinners.... have personal preferences largely due to our framework of learning/growth/maturity in life.
