    Please remember that you should record your MP3s at 11Khz for slim.swf to play correctly

    A quick example follows:
</p>

<object type="application/x-shockwave-flash" width="400" height="17"
    data="/slim.swf?song_url=/data.mp3&song_title=This%20is%20the%20title">
    <param name="movie" value="/slim.swf?song_url=/data.mp3&song_title=This%20is%20the%20title" />
    <param name="quality" value="high"/>
    <param name="bgcolor" value="#E6E6E6"/>
</object>

<p>
    Remember that if this is not working for you, you should most probably point the song_url GET parameter to a real MP3 file that should be reachable through the web server.
