Simply explained below, since all we have to do is get to the song's LRC lyrics address, so useful only 2829 of this tag.
and encode and decode inside the stitching up is mp3 download address, as in this example

http://zhangmenshiting.baidu.com/data2/music/12762845/ Ymrqamdua21fn6nndk6ap5wxcjlrmg1xljhobwibmgpjk5ztmwizcwrjz5lqbgyelgkwlztubgljz5lka2uanwsxy1qin5t1ywbmzw5ocglhawdnbgtqbze $12762845.mp3?xcode=e6b69cf593ea22ac9d2b9314e565fc0caf85125f065ce3e0&mid=0.31929107437537

is the download address, but the sound quality is too poor, there is time to study this.
Keep saying the lyrics, note the 2829 in the lrcid tag.
http://box.zhangmen.baidu.com/bdlrc/This is Baidu LRC lyrics storage address,
Then the lyrics address of this example is HTTP://BOX.ZHANGMEN.BAIDU.COM/BDLRC/28/2829.LRC
See, the two numbers after the lyrics address are calculated by dividing lrcid by 100, which is the first number, and then the second number is lrcid, followed by a suffix. The LRC is done.
It's easy to get the LRC address, just request the address, and then write the retrieved content to the file.
Okay, that's probably it, here's the code:

Import osimport os.pathimport reimport eyed3import urllib2import urllibfrom urllib import urlencodeimport sys import Osrel Oad (SYS) sys.setdefaultencoding (' utf8 ') Music_path = r "E:\music" Lrc_path = r "E:\LRC" Os.remove (' Nolrc.txt ') os.remove ( ' Lrcxml.txt ') the_file = open (' Lrcxml.txt ', ' a ') Nolrc_file = open (' Nolrc.txt ', ' a ') for Root,dirs,files in Os.walk (music_ Path): For filepath in Files:the_path = Os.path.join (Root,filepath) if (The_path.find ("MP3")! =-1): Print The_path the _music = Eyed3.load (the_path) The_teg = The_music.tag._getalbum () the_artist = The_music.tag._getartist () The_title = t He_music.tag._gettitle () # print The_teg # print The_title # print The_artist b = the_title.replace (", ' + ') # Print b A = The_artist.replace (', ' + ') #print UrlEncode (str (b)) if Isinstance (a,unicode): a = A.encode (' UTF8 ') Song_url =  "Http://box.zhangmen.baidu.com/x?op=12&count=1&title=" +b+ "$$" +a+ "$ $" the_file.write (song_url+ ' \ n ')  page = Urllib2.urlopen (song_url). Read ()Print page Theid = 0 lrcid = re.compile (' 
 
  
   
 (.*?)

  
 ', Re.  S). FindAll (page) HAVE_LRC = True if lrcid! = []: Theid = lrcid[0] else:nolrc_file.write (the_title+ ' \ n ') HAVE_LRC = False Print Theid if have_lrc:firstid = Int (theid)/100 lrcurl = "http://box.zhangmen.baidu.com/bdlrc/" +str (Fir Stid) + "/" +theid+ ". LRC" Print Lrcurl LRC = Urllib2.urlopen (Lrcurl). Read () if (Lrc.find (' html ') = =-1): Lrcfile = open (LR   c_path+ "\ \" +the_title+ ". LRC", ' W ') Lrcfile.writelines (LRC) lrcfile.close () else:nolrc_file.write (the_title+ ' \ n ') The_file.close () nolrc_file.close () print "end!"

Useful first step request is obtained in the end is XML format, so originally wanted to parse XML to get lrcid, but in the implementation process encountered a variety of problems, other also easy, in this together wasted time the longest, tangled not fruit, can only use regular expression to get ... Just to show or not to be a fine apprentice.
