Two very good books I have read that critique modern worship music are "Why Johnny Can't Sing Hymns: How Pop Culture Rewrote the Hymnal" by T. David Gordon, and "All God's Children and Blue Suede Shoes: Christians and Popular Culture" by Ken Myers. I think they address this issue very well!
The mainline church sadly demonstrates that the 'jesus' they reference is not the Jesus of the Bible but rather one of their own making. The WWJD banner in the accompanying photo betrays at best, a misunderstanding of Jesus' ministry. He had a singular mission and focus: reconciling sinners to God - period. It's not 'What Would Jesus Do?', but rather what has Jesus done! Even Jesus' humanitarianism pointed to that. Jesus uses the coin with Caesar's inscription to illustrate the utter distinction and separation of His Kingdom from the kingdom of this world. Perhaps Rowan should study instead Jesus' answer to the covetous man who wanted his brother's inheritance (Luke 12:13 ff.). The OWS crowd, on the other hand would do well to ponder Psalm 50:16-22.
I do not know Dr. Hoffman's credentials, nor why SermonAudio found this article newsworthy. Nevertheless, it seems the NT writers, more often than not, believed the Septuagint to accurately convey God's word, as they quote from it profusely. Paul specifically quotes the tenth commandment in Romans 7:7, and clearly understands it to convey the meaning of the Greek term for "coveting" (epithumia). For my money, I will take Paul's inspired interpretation over that of a writer for the Huffington Post.
