 Because it really needs to be, and Luther and Zwingli and a lot of the reformers had some interesting things to say about music. They said the purpose of the music is to honor God. If you're focused on the music, you're not focused on God. The music should be helping you to be focused on God. And if you're thinking about the person performing or singing or playing instruments, then you're not focused on God anymore. So that would be a red flag if the church has a large focus on music.
