Song Slides: Design
Make sure you're on one of the song slides. Then go to VIEW>Slide Master...
Select the title box. Then under HOME, change the font size (reduce to 60-66) and align to the right.
Change the style to something else that stands out.
Make the text box wider, so it lines up with the width of the title box on the right, and align the text in the box to the right.
Also change the font color inside to white, and make the case "Sentence", not all caps. Pump up the size to 36-40.
Close Slide Master view. All your song slides should look like this now...
