html5音乐播放器（chrome测试通过）
html5出来已经很久了，众所周知html5支持播放音乐和视频，作为一个html5网页的开发者，一直都想做一个html5的音乐播放器，同时也增加对javascript的认识，我利用空闲的一段时间开发了一个javascript版本的html5播放器，由于马上又有事情做，这个版本只具备的一部分的功能，欢迎大家一起交流，完成所有的功能。靠，发现我太唐僧了，不说废话直接上代码了

应用说明：首先确保你已经安装了chrome，而且电脑上面有mp3格式的音乐。
进入页面之后点击add按钮，把mp3的全路径copy到对话框中，这样你的音乐就会出现在页面上了，点击一个播放，然后就会开始列表循环播放。
