There are several Worship Lyric PowerPoint software out there to choose from but you must consider the following.
1. Will it text support motion backgrounds?
2. Will it support text borders (to place white font over clouds)?
3. Does it have a way to catogarize songs for quick access?
4. Is ther support for future upgrades and help?
If you can answer these questions with "yes" then you have found your tool for the next Sunday service! The one I recommend is http://easyworship.com/
Also, just as important as the software you will need a good jumpstart with lyrics and backgrounds. You can go here to get those http://worship-lyrics.com.
