For my song book I needed the same thing, and additionally the
possibilty to enforce starting on an odd page (for songs three or more
pages long where page turning is better done after the first page than
after the second one). Here's my solution:

% force the following content to appear on an odd page:
\newcommand{\ForceOddPage}{%
        \ifodd\value{page}%
        \else%
                \thispagestyle{plain}%
                \rule{0pt}{1pt}%
                \newpage%
        \fi%
}
% begin a new page and make sure the next content appears on an odd page:
\newcommand{\newpageForceOdd}{\newpage\ForceOddPage}
% force the following content to appear on an even page:
\newcommand{\ForceEvenPage}{%
        \ifodd\value{page}%
                \thispagestyle{plain}%
                \rule{0pt}{1pt}%
                \newpage%
        \fi%
}
% begin a new page and make sure the next content appears on an even page:
\newcommand{\newpageForceEven}{\newpage\ForceEvenPage}
