脚本下载谷歌高质量的音乐
谷歌的音乐一上线，就有人搞出来脚本下载，不过他这个脚本是Python3.0的，我不太喜欢Python3.0，就将其改成了2.5的了，且我喜欢下载整张专辑，也就改成了给脚本专辑地址了，避免搜索。

下载完了以后用mutagen自带工具mid3iconv可以转换mp3的tag编码，不过这里有个小问题，就是对于谷歌高质量音乐有一点不爽，谷歌音乐都是自带歌词的，这个工具不能转换歌词，我就改了改，让他可以该歌词编码了，这样iTunes等只支持unicode的就没问题了，ipod touch/iphone中也可以真长看到歌词了。其实主要就是改了很小一点，原来mid3iconv只是修改T开头的tag，我加上了对歌词所在的”USLT”tag的处理就OK了，代码如下：

就明白了。这个伤是我在两星期前踢球的时候受的，当时是我带球的时候，被对方队员从后面踢到膝盖，然后我就重重摔倒了。就在我摔倒的时候，一阵疼痛从左腿传来，我立刻就站不起来了。过了几秒钟，痛苦有所减轻，我以为只是一般轻伤，就没在意继续比赛了，虽然后面我也没有再怎么跑，我觉得这也是我伤势加重的原因。等踢完比赛以后，我当时觉得应该没事了，就吃饭，休息，去实验室了。可是到了实验室我坐了一会，想站起来的时候就发现，我已经站不起了。左腿不能伸直，也不能太弯曲。根本不敢用力，否则就是巨痛。
