LRC 歌詞秀的關鍵原理是什麼？如何是什麼？我現在理解的就是：
從LRC文件中讀取[00:20.63]之類的時間標簽，和播放器正在播放的時間作比較，然後，使用 Timage或者是 TPaintBox 來TextOut()；但是，如何提取LRC歌詞文件中的時間標簽？因為一個 LRC 文件中，一行的歌詞可能是這樣的： [02:19.96][01:08.86]圈圈圓圓圈圈
[02:22.62][01:10.55]天天年年天天的我深深看你的臉
[02:27.67][01:15.21]生氣的溫柔埋怨的溫柔的臉
[02:30.83][01:23.48]不懂愛恨情仇煎熬的我們
[02:38.44][01:27.19]都以為相愛就像風雲的善變
[03:21.11][02:42.81][01:31.44]相信那一天抵過永遠如何提取時間標簽並且按照時間順序來排序？
