你总是如此如此如此的冷漠
我却是多么多么多么的寂寞
事隔多年你我各奔东西
我会永远把你留在生命里
我曾用心的来爱着你
为何不见你对我用真情
无数次在梦中与你相遇
惊醒之后你到底在哪里
不管时光如何被错过
如果这一走你是否会想起我
这种感觉往后日子不再有
别让这份情换成空
你总是如此如此如此的冷漠
我却是多么多么多么的寂寞
事隔多年你我各奔东西
我会永远把你留在生命里
我曾用心的来爱着你
为何不见你对我用真情
无数次在梦中与你相遇
惊醒之后你到底在哪里

这种感觉往后日子不再有
别让这份情换成空
你总是如此如此如此的冷漠

呵呵，这美人迎面而来啊，尤其全屏的时候，感觉完全扑过来了呢{:4_173:}

漂亮的制作，欣赏亚伦老师好帖{:4_204:}
这个歌词好像不是完全同步的，提前了呢。记得好像对这个时间可以批量调的？
