Music gets way too much credit as a form of God-worship. I believe that music (and any other art, Christian or otherwise) is always worship, but worship can be many other things than music. So why do we do it so regularly? What is its value spiritually? Why is it that only in church we find ourselves singing with a bunch of strangers? It's quite queer, really.
Perhaps it is because music is always “just and good” (Psalm 33:5), even in the midst of imperfect singers and musicians. I think God created music as a sort of gift that allows humans to create something out of nothing. Think about it--songwriting is essentially creating something out of thin air--not from compiling other pre-existing parts and pieces (sans cookie-cutter pop music), but something that only exists because its wholeness exists.
When we get together and sing as a church, it is our time to worship God with each other. It's not "my time" to worship God. Rob Bell said something about the significance of submission in corporate worship--Submitting to each other (singing together) for the greater good of the wholeness of the song and its rhythms and melodies. What a great metaphor for the work of the people: The congregation is held in submission to each other by the song's melody, tempo, and key. And the band members are held accountable to the music by each having their own role in creating the music, and therefore "leading" (although I don't like that word).
If somebody deserts their role for the sake of glorifying themselves, the song (the good work) ceases to exist.
