mp3spider is a free shell script to help you download mp3 from  mp3.baidu.com, it may be useful only for Chinese user. It is free, it may have issues when baidu update their web page. So I can not not make sure that it can work any time.                           
Any suggests, bugs, improvements, please tell me. thanks so much   
  Have a fun :)       

mp3spider can work on Linux only(it may work on Unix, but I did not try it). following these steps:
1. download the latest script
wget http://www.shaohui.org/downloads/mp3spider.sh  
2. select the mp3 category
...
#SOURCE=http://list.mp3.baidu.com/lis ...     
# 中文金曲榜
#SOURCE=http://list.mp3.baidu.com/....
# 校园歌曲
#SOURCE="http://list.mp3.baidu.com/list/...   
# 轻音乐
SOURCE="http://list.mp3.baidu.com/list/...
# 欧美金曲
...
uncomment any one of them, it is the source of mp3 song, we will fetch a mp3 list from this URL.
3. run the script
mp3spider.sh will create a directory "mp3" to save your songs, I will cost many disk spaces, so before you run this script, you need to make sure you have enough space.
bash mp3spider.sh
it will cost a very long time, you can run it in background, and do something yourself. check it after one day.
