I really like those songs by themselves but coupled with people raising their hands around looking like zomblies or lunatics makes me barf too.
I prefer a much more "traditional" service with an organ, choir .. the like. Sometimes the choir can sing songs so beautiful they make my heart swell up with joy -- a much different feeling than the "being in the midst of zombies" feeling.
But I'm sure you don't share my view -- i just wanted you to know that they make even some Christians barf.
