描述：欢迎使用本脚本.本脚本使用户在线收听音乐的同时欣赏自动跟随的歌词，还可以随时控制暂停，播放。
该脚本的特点:应用Javascript的层技术，和一些function（）使播放音乐的同时实现歌词的相应滚动。
使用realplay的rm格式音乐使下载的同时进行播放。
（该特殊效果对IE4以上都有效。）

How can I just let you walk away <br>
Just let you leave without a trace <br>
When I stand here taking <br>
Every breath with you <br>
You're the only one <br>
Who really knew me at all <br>
How can you just walk away from me <br>
When all I can do is watch you leave <br>
'Cause we've shared the laughter and the pain <br>
And even shared the tears <br>
You're the only one <br>
Who really knew me at all <br><br>
So take a look at me now <br>
Oh there's just an empty space <br>
And there's nothing left here to remind me <br>
Just the memory of your face <br>
Take a look at me now <br>
'Cause there's just an empty space <br>
And you coming back to me is against all odds <br>
And that's what I've got to face <br><br>
I wish I could just make you turn around <br>
Turn around and see me cry <br>
There's so much I need to say to you <br>
So many reasons why <br>
You're the only one <br>
Who really knew me at all <br><br>
So take a look at me now <br>
'Cause there's just an empty space <br>
And there's nothing left here to remind me <br>
Just the memory of your face <br>
Take a look at me now <br>
'Cause there's just an empty space <br>
But to wait for you is <br>
All I can do <br>
And that's what I've got to face <br>
Take a good look at me now <br>
'Cause l'll still be standing here <br>
And you coming back to me is against all odds <br>
That's the chance I've qot to take <br><br>
Take a look at me now </p>
