Here is a snippet from a Worship Blog about why God wants us to sing. I found them relevant and purposeful so I'm re-posting... (See the original post here) from Bob Kauflin - Singing can help us remember words.
In the church we should use melodies that are effective.We should sing words that God wants us to remember. The lyrics to our songs should reflect the broad themes of Scripture. We should seek to memorize songs. - Singing can help us engage emotionally with words.
We must differentiate between being emotionally moved and spiritually enlightened. Singing should be an emotional event. We need a broad emotional range in our songs. - Singing can help us use words to demonstrate and express our unity.
Every voice in the church matters. We should seek to sing songs that unite, rather than divide, the church. Musical creativity in the church has functional limits. We must be clear that it is the gospel, not music, that unites us.
"1 Chronicles 16:23 Sing to the LORD, all the earth; proclaim his salvation day after day."
