With that kind of a holier than thou attitude, you might not have to worry about leaving. You may not get there. Won't you feel funny if that's the kind of music played in Heaven? LOL!
I've been to many churches and have listened to it all. It's not about the music. It's about the Worship! The condition of a man's heart. Our love for God. That is what God looks at. :o)
So now if I have musical tastes that differ from yours, I'm going to hell? I can't find the passage in the Scriptures that says, "If thou findest not pleasure in the repetitious praise music of the twenty-first century after Our Lord's Resurrection, and if likewise thou dost favor the songs and musical instruments that were raised to His glory in times closer to His life on earth, thou shalt surely be condemned, for thou art being 'holier-than-thou' and for this there is no forgiveness." Can you cite the verses for me? It just doesn't seem to be in my KJV.
