Lilypond makes gorgeous music. However, getting things besides music to look good is painful at best and sometimes impossible. I spent hours trying to figure out how to get a good looking lead sheet setup (music, chord name, lyrics). Especially font sizes and spacing. Ugh. Good luck getting an annotation (such as "intro" or "chorus") anywhere less than about 2em from the top of the staff...

I think they've changed things in the five years since then, so I think I'd have to do it all over again.
