clone second cousin Danny has another post that I feel like I could have written. What I mean by this is that (1) I happen to agree with everything he says, (2) the things he's most interested in emphasizing are what I think is most important, and (3) the qualifications he makes to his major points are all things I would want to be clear about so that the major points wouldn't be misunderstood. It gets into the purpose of public worship, the connection of being filled with the Spirit and singing songs to each other, and the significance of all that for how we should do public worship. It's a thoroughly balanced post. Also, check out the comments to see why I think the view that public worship is about intimacy with God is not only wrong but even contrary to the real purpose of public worship.
