I was involved in a conversation recently about music in worship, and whether or not certain beats were inherently sinful. I said no, and here is why;
I think we need to be careful not to place the sin in the "thing". Sin is something that *people* do. Rhythms and melodies and harmonies can be used in ways that do not glorify God, but they also can and should be used in ways that DO glorify Him. I don't think there is any such thing as a "sinful" beat, just sinful "beaters". But there are certainly "beats" that don't belong in the worship of God, since they are made for other purposes. Some music works really well when you are alone with your spouse with the lights down low, but it wouldn't be appropriate in a congregation.
