Church Songs

I am wondering, what makes a good church song? Before I go ahead on this topic, I would like you to read the last page of the January 2007 edition of The Briefing. If you can't get it, I'll summarise it. Ian Carmichael, in saying that we should put a blanket ban on Hillsong music, gives 3 reasons:
1) When singing their songs, we publicly endorse them. And we don't want to be doing that do we?
2) When singing their songs, Hillsong financially benefits through royalties and other stuff. We don't want to be bankrolling harmful teaching. (the edition makes it clear that the teaching of Hillsong is not great, actually, pretty bad.)
3) When singing their songs, we compromise our theology, mainly because some of their songs are way off target, or even the good sounding ones mean different things to different people due to their ambiguity.

I wanted to point you to Trevor Hodge's recommendation that "Blessed Be Your Name" (by Matt Redman) is a good song. Also, I want to draw your attention to Trevor's recommendation of "Here I am to Worship" (by Tim Hughes) - he qualifies this recommendation with: "Needs to be balanced with teaching or songs that reminds us that worship is all of our life, not just our songs."

My question is this: does a good song need to be "balanced" by anything - or should they be able to stand on their own? No doubt there are many songs out there that praise God for his creation. Is it a bad song if it does not sing of his redemption of us in Jesus?

The other thing is the Blessed Be Your Name song (which I actually find really good musically). I would like you to read Andy Judd's case study of this song on the Garage Hymnal site:
Case Studies of Questionable Lyrics He ultimately gives the "pass mark" to this song because the major questionable line of "You give and take away" (taken from Job) "My heart will choose to say... Blessed be your name" makes sense in that the saints can praise God because by definition, that is what we do (because of God's grace and Holy Spirit). BUT since the song does not qualify the line of "My heart will choose to say" with words to the effect of "by your grace" or "by your Holy Spirit" does this make this a bad song?

In any case, would trying to fit such qualifying lyrics render the song so unsingable, that it becomes a bad song on grounds of musical lameness or unsingability. What are your thoughts? What makes a "good" church song? What are some examples that you think are good and not-so-good songs?
