  <p>I am making a iPhone app and there is a feature to display song lyric while playing a song. It came up with 2 questions.</p>
  
  <ol>
  <li><p>What's the industry standard format of song lyric which can be used for this? I heard there is a xml format with song lyric content and timeline information, does anyone know this?</p></li>
  <li><p>Assuming I got this xml file or other format of song lyric, how can I use it while playing a song? </p></li>
  </ol>
