I don’t particularly care if a band is Christian if the music is good. Firstly, a sizable chunk of the lyrics of bands I listen to are fictional or based on fiction; why be upset about one mythology and not any others? Secondly, I enjoy a lot of baroque music; good luck getting away from Christianity centered music there.
I haven’t done it yet, but I’ve made a mock-up for a custom print t-shirt that has Bach’s picture on the front, and on the back is written “Bach is better than your favorite band.”
It’s funny because it’s true.
