制作人：亚伦
OP：亚伦影音工作室
看时间如水流
梦该走就会走
叹青春还不够
飘渺流年似水又虚度几个秋
叹光阴已陈旧
爱该留的会留
念往事难回首
只能无可奈何用回忆来拼凑
都说时光最难留
我们都难免念旧
多少遗憾在游走
情深剩下几分愁
都说时光最难留
现实像一杯浊酒
期望已被偷走岁月染白头
叹光阴已陈旧
爱该留的会留
念往事难回首
只能无可奈何用回忆来拼凑
都说时光最难留
我们都难免念旧
多少遗憾在游走
情深剩下几分愁
都说时光最难留
现实像一杯浊酒
期望已被偷走岁月染白头
都说时光最难留
我们都难免念旧
多少遗憾在游走
情深剩下几分愁
都说时光最难留
现实像一杯浊酒
期望已被偷走岁月染白头
期望已被偷走岁月染白头
