These songs are ones I used to hear at Mass starting in the 80's.  Now that I do not attend church anymore, I still love to hear these songs, as they inspire me and make me feel peaceful.  I even listen to them while driving sometimes when I want a break from my usual fast-moving country and pop stuff.  John Talbot is a very smooth singer to listen to -- a diversion when one needs to get away from the noise of the modern world.  BTW, you don't have to be Catholic or any other religion to benefit from the effect these songs have on most people.
