今天做了一个播放器，不过美工没学好，所以样式有点丑，不多说贴码。
首先给个做好的界面：

1.首先是css，文件名：music.css

body{
margin:20px;
font-family: Verdana, Geneva, Arial, Helvetica, sans-serif;
font-size:12px;
}
#musicList{
	
}
li{
   
   list-style: url(../images/heart.png) outside circle;
   line-height:20px;
   padding-bottom:3px;
   vertical-align: middle; 
}

.float_r{float:right;}
.float_l{float:left;}
.playMode{text-align:right;}

.songStyle{
	width: 300px;
	margin-bottom:20px;
	border:1px solid #96C2F1;
	background-color: #EFF7FF
}
.songStyle h3{
margin: 1px;
padding: 1px 1px 1px 10px;
background-color: #B2D3F5;
height: 24px;
}
.playDiv{
	width: 610px;  
    margin-bottom:10px;  
    border:1px solid #92B0DD;  
    background-color: #FFFFFf  
}
.currentMusic{  
    background-color: #E2EAF8;  
    height: 24px;  
	width:100%;
}
.currentSpan{
	padding-left:3px;
}  
.lastMusic{
 background-color: #E2EAF8;  
 text-align:center;
}
.lastMusic img{
	width:32px;
	height:32px;
	cursor:pointer;
}
.infoStyle{
	margin-left:10px;
	width: 300px;
	margin-bottom:20px;
	border:1px solid #96C2F1;
	background-color: #EFF7FF;
}
.infoStyle h3{
margin: 1px;
padding: 1px 1px 1px 10px;
background-color: #B2D3F5;
height: 24px;
}
.info{
	width:49%;
}
.picInfo{
	width:49%;
	margin-right:2px;
	height:100%;
}
strong span{
	margin-left:4px;
}
.info div{
	padding: 10px 0px 10px 10px;
	font-size:12px;
}
.liOn{
	background-color:#E3E197;
}
.Gray
{
 filter:alpha(style=0,opacity=30,finishopacity=30);
}

2.javascript文件，文件名:music.js

记住引入jquery.js,文中的图片均来自网络。
到这儿，基本都做好了：
