To the rock and roll lover, we became a rock and roll band. To the heavy metal lover, we became a heavy metal band. To the country music lover, we became a country band. All we are doing is translating it into a language which our audience understands. God made human beings, and God made music.
Human beings become sinful by the things they say and do.
God can do the same thing with music. When God changes a human being, on the surface that human being may appear exactly the same, but his heart is changed. When God changes music, it may sound the same, but the heart of the song is changed. You can tell a Christian by the things he says and does. You can tell Christian music by the things it says and does.
