<P>陪你度过漫长岁月</P>
<P>演唱：陈奕迅</P>
<P>走过了人来人往 不喜欢也得欣赏</P>
<P>我是沉默的存在 不当你的世界 只作你肩膀</P>
<P>拒绝成长到成长 变成想要的模样</P>
<P>在举手投降以前 让我再陪你一段</P>
<P>陪你把沿路感想 活出了答案</P>
<P>陪你把独自孤单 变成了勇敢</P>
<P>一次次失去又重来 我没离开</P>
<P>陪伴是 最长情的告白</P>
<P>陪你把想念的酸 拥抱成温暖</P>
<P>陪你把彷徨 写出情节来</P>
<P>未来多漫长 再漫长 还有期待 </P>
<P>陪伴你 一直到 故事给说完</P>
<P>让我们静静分享 此刻难得的坦白</P>
<P>只是无声地交谈 感觉幸福 感觉不孤单</P>
