I think when you get into music and certain songs you should never be stuck in a box. The song should be chosen by the moment or atmosphere you are in. Too many people get stuck on what they like and what they want to hear. Why not listen to the spirit and what God is calling for at the moment. Whether your pentecostal, baptist whatever. Listen to God and a simple 1-4 progression when done at the right moment will sound like angels singing.
I personally love songs like how great is our god, here i am to worship, you are my all and all. I also like gospel stuff, but if you play some of the ccm stuff at the wrong moment you are going to put folk to sleep!
It's all about the moment and what's going on at the moment not what you can play and how phat you can make the song!
