Personnally, I'd recommend *not* to set between-system-space and
between-system-padding.

This is because LilyPond does not have enough place to:
 -print a new system and the lyrics
 -*and* respect your bottom-margin
 -*and* respect your between-system-space.

Setting bottom-margin can dramatically influence the number of pages:
in the example below, a value of 4\cm prints three pages instead of
two.

%%%%%%%%%%%%%%

\paper {
  bottom-margin = 5\cm % try with 4\cm
  annotate-spacing = ##t
}

notes = { f1 }
\addlyrics { blah }
\addlyrics { blah }


music = <<
\new Staff \notes
\new Staff \notes
\new Staff \notes
\new Staff \notes
>>

\book {
  \score { %1
    \music
  }
  \score { %2
    \music
  }
  \score { %3
    \music
  }
}

I think this is a bug, I'll file a report. It's the same no matter
what font is used.

See a possible solution below.

You can include an empty element in your markup:

\markup {
  \column {
    \null %% This adds an empty element above the text.
    \fontsize #7  {Your text}
  }
}
