Praise is a powerful weapon, in that, it allows us to have a vehicle to use in releasing faith. The faith we release is in Jesus' Victory over the enemy. Hallelujah is glorying in Jesus' Triumph over the devil and darkness. Satan knows, as a fallen worship leader, what this praise will do and what it's all about. He knows that praise and worship generates faith that takes you higher and higher into the glories of God. It got you more and more views of Him. When we praise Jesus, God dispatches angels to bring us messages about Him. These messages take us even higher into knowing our Father. The devil fights worship with every alternative imaginable, especially music. He never wants your soul continually focused on the Victory of Jesus. If it, your soul, is continually focused on Jesus you will begin to see tremendous growth and light. The devil will be exposed and cast out and the expansion of the kingdom of God in you, in your soul, shall take another giant step in securing Jesus as Lord in you, to you, and through you.
