please comment on gist if you have any questions.

How to install:
1. put this file on lua/intf/
2. enable extra interface: luaintf (Settings[Show all] -> Interface -> Main Interfaces -> extract modules='luaintf'[make the 'Lua interpreter' checked])
(important: extraintf=luaintf not lua)
3. set lua interface to this file name: All Settings -> Interface -> Main Interface -> Lua -> Lua interface = lyrics
4. Settings - subtitle/osd - make "enable osd" checked.
如何启用：
1、将本文件放在 lua/intf/ 文件夹下
2、设置（显示所有）-界面-主界面-扩展界面，填入 luaintf，并勾选 Lua interpreter(勾选会自动填为 lua, 需要手动改成 luaintf)
3、设置（显示所有）-界面-主界面-Lua，在 Lua 界面 字段填入本文件名: lyrics
4、设置-字幕/OSD-确保 "启用 OSD" 勾选，下方可以设置字体
