I am using Kugou 2010 and the problem you described has never occurred. Generally speaking, if you double-click a song, it will automatically download the song and lyrics. The default song name and lyrics name are the same. Lyrics files are stored in the Kugou installation program directory. You can connect the mp3 to the computer, click the copy tool on Kugou, and copy the songs you selected into the mp3. In this whole process, it will copy the song and lyrics together and the file name will be the same.
