I've probably attended 10 or more worship arts conferences since I began leading worship regularly over 15 years ago. For worship leaders, gatherings like these are as valuable as any professional conference is for professionals in any field. The content is what you would expect--worship leaders teaching other worship leaders how to lead worship better. Every time I go to one of these conferences, there is so much content to take in over the space of a few days that it is truly overwhelming.
Fairly often, someone comes up to me after a worship service and wants to know the name of one of the songs we've just led, so I've been thinking it might be a good idea to publish our worship set lists each week, so that people who are interested in learning the songs can know in advance what we're going to be playing, and listen ahead of time. Or, if a particular song strikes them as particularly meaningful, they can check the set list to find the name (and possibly the artist associated with the song).
