Are you content with your worship?  Is contentment what praise and worship is all about?  Some people love to go to worship because the music is "lively" or "energetic".  They LOVE the music; it energizes them.  They jump, laugh, sing la-la-la and enjoy themselves.  It's an uplifting experience.  Psalm 33 is a Psalm about worship and you'd be surprised at what it has to say; that is, if you are one of those who go to church just to get a high and feel good during the week.  Contentment in worship should be about the content.  Find how the content of worship can make you content for the rest of your life!
