title: What is proper way to specify relative path to file in M3U playlists?
body: <p>What is proper way to specify the path to mp3 file in M3U playlists, for use playlists in hardware players, like Compact &amp; Shelf Stereos, Micro Component Systems, Car Audio Players?
  I understand the path should be relative, for more reliable playback. For example, Windows Media Player m3u playlist have two dots before the leading back slash:</p>
  
  <pre><code>#EXTM3U
  #EXTINF:0,Artist - Track Name (Mix).mp3
  ..\My Album\Artist - Track Name (Mix).mp3
  </code></pre>
  
  <p>Does this dots and leading back slashes make any sense for hardware players?</p>
