There is 'clear'...then there is 'interesting' or 'attractive'. If you have a recent copy of Windows, you probably have quite a selection to choose from. Then you need to decide on Serif or Sans-Serif. Arial is one 'standard' sans-serif font. Tahoma is another...and there are hundreds more.

In Serif, I like Georgia, Palatino Linotype, Perpetua....and dozens more. It is possible to mix fonts in such a project...one for titles, another for lyrics...but that is up to you.

You should (if you DO have Windows) have a font management control under Start-> Control panel. Take a look...and typing in 'fonts' in Google will take you to many places with wide assortments....most of them free.

(I have...ummmm...7000-8000 or so fonts squirreled away...how would *I* know what I like? *grin*)
