In my experience, I've noticed that we often focus on Bible study, small group or Sunday School curriculum, or the pastor's sermon to be the "teaching part" of our spiritual development. The music is the "worship" part, and if we give any thought to it at all, it's because of how it makes us feel.

But the truth is, the songs we sing, much like "In the Tiki Tiki Tiki Room", can be an important part of "explain this!"
