I don't see why we can't praise God with loud music. Psalm 150 talks of doing just that.
We need to make sure our focus is on God rather than on the music, and there is a danger with more modern songs to become very repetitive and induce a state of euphoria that is then confused with a spiritual encounter, which in turn leads to all sorts of problems. But it's just as easy to fall into the mindset that because we are singing a traditional hymn we must therefore be worshiping God, when the truth might be we are singing the hymn and following a prescribed order of service while thinking more about the work we need to do when we get home and remembering the really good evening we had last Friday. I'm sure the sound of 1000 people singing "Praise my soul the King of heaven" accompanied by a cathedral pipe organ is every bit as loud as 250 people singing Bethel-style drivel like "jump, jump, jump jump in the river" accompanied by an electric guitar.
