Most likely the LaTeX code produced by Songwrite contains something
like
\usepackage{ae}
Replacing that by
\usepackage{lmodern}
should solve your problem and lead to better results wrt fonts.

Great! I found where Songwrite writes this command in its code and this solves the issue without the (uggly) patch I did before :). I'll report this to the upstream author and propose you close the bug.
Thanks, JM.
