Just to throw my opinion into the arena....
I think we contemporary Christians are using the word "worship" incorrectly. I think we often say worship when what we mean is 'music'. I think we should be using all of our time, whether among the congregation or at home, at work, at school, at play... to worship God. (Romans 12)
But, in terms of music, I think a lot of what is popular contemporary music really is lacking in value for use in the congregation (but not necessarily lacking in value elsewhere, although of course the need to "entertain" could be debated ad nauseum!). It wouldn't be fair to highlight individual songs, though, because frankly any one here would be able to identify a time when it's use was particularly appropriate. It is when we have sets/entire services which use these songs. An indivividual song might be quite appropriate, but we need to look at our choices across the board.
I am guessing a lot of posters here are involved with music ministry in our churches? Perhaps over the coming weeks you can look at your music sets and count the number of songs which refer to Jesus Christ by name, or to His blood and our salvation. It is the Name of the Lord which I have seen disappearing quite conspicuously. Case in point? A worship leader (at my church) had a bracket of 3 songs one week with repetitions etc... not a single mention of Jesus' name. Like I mentioned, the individual songs might be okay for a specific purpose, but I think 3 (or 2 or 4 etc) in a row is probably leading us away from true congregational worship of Jesus.
Music is wonderful, and I believe God is thrilled by the joyful noise we make especially when we come together in Jesus' Name as a family and agree to praise Him. But music is also really emotive, and I feel we can be numbed by it's beauty while lulled into a spiritual coma due to it's lack of depth.
IMO, that's the bottom line of all we do in worship (whether music, prayer, supplication, marriage, child-rearing, working etc etc etc) .... does it have substance? Does it have depth? Does it exalt the power of Christ and His unfailing love for us?
Apologies if I rub anyone up the wrong way.
Cheers,
Ruby
Just thought I should add... there's a standard that I'm writing about here to which I aspire - I am not under the impression that I've reached perfection yet!
