On my side bar I maintain a link to Bro. Jason Skipper's "A Minister's Musings". I'm always interested in topics on music & singing and am linking here to his Music in the church.
In part, Bro. Skipper writes:
"Faithfulness to Scripture is absolutely essential...Music is a teaching tool. We are to use it to admonish/warn one another...Our songs should always remember the Lord, His glory, and His goodness to us." Click the link above and check it out. His blog also contains a link to Bob Hayton's "Fundamentally Reformed" blog site, which got him musing on the subject.
