歌词的显示，对一个媒体播放器来说是很需要的，特别是对有网络功能的产品，如果还要自己手工去找歌词，那么就不够充分利用其网络功能了。

如果能让其自动下载歌词，那么就是一个更酷的feature了。

这里列一下“千千静听”的歌词自动下载的功能，值得嵌入产品借鉴。

所抓的数据包：

1、根据 artist, title 来发送 http get 请求：

GET /dll/lyricsvr.dll?sh?Artist=730068006500&Title=E26CAF652B73&Flags=0 HTTP/1.1
Referer: http://ttlrccnc.qianqian.com/ Accept: image/gif, image/x-xbitmap, image/jpg, image/pjpeg, text/html, text/xml, */*
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Host: ttlrccnc.qianqian.com
Connection: Keep-Alive
Cache-Control: no-cache

HTTP/1.1 200 OK
Connection: close
Content-type: text/html; charset=UTF-8
Content-Length: 179
Date: Fri, 26 Jun 2009 01:45:51 GMT
Server: Apache 1.3.29

<?xml version="1.0" encoding="UTF-8" ?>
<result>
.<lrc id="7956" artist="S.H.E." title="........."></lrc>
.<lrc id="235751" artist="S.H.E" title="........."></lrc>
</result>

2、根据得到的歌词列表 ID 号，发送 http get 请求：

GET /dll/lyricsvr.dll?dl?Id=7956&Code=2013547666&ci=6a661c70523225565316101c0260121f21542a5559264444141c464808425c5353011d01 HTTP/1.1
