我爱你爱你爱你爱你就是把你爱
今生今世谁也不能把你来替代
你可知道我已为你寻觅多少载
终于在这美好时刻你向我走来
我想你想你想你想你想的好无奈
梦里梦外都是你我为爱而精彩
这个世界人流如织人潮也如海
能让我们邂逅真是上天的安排
你就是我的爱我只为你存在
就算天荒地老这份痴情永不改
紧紧拉着你的手永远也不放开
直到青丝变成白发依然不倦怠
你就是我的爱我只为你存在
无论日升月落一颗痴心也澎湃
只想每分每秒都能拥你在心怀
今生爱不够我来世还把你期待
我想你想你想你想你想的好无奈
梦里梦外都是你我为爱而精彩
这个世界人流如织人潮也如海

你就是我的爱我只为你存在
就算天荒地老这份痴情永不改
紧紧拉着你的手永远也不放开
直到青丝变成白发依然不倦怠
你就是我的爱我只为你存在
无论日升月落一颗痴心也澎湃
只想每分每秒都能拥你在心怀
今生爱不够我来世还把你期待
你就是我的爱我只为你存在
就算天荒地老这份痴情永不改
紧紧拉着你的手永远也不放开
直到青丝变成白发依然不倦怠
你就是我的爱我只为你存在
无论日升月落一颗痴心也澎湃
只想每分每秒都能拥你在心怀
今生爱不够我来世还把你期待
今生爱不够我来世还把你期待

好可爱的小乐队，还用了遥控器播放器。这个制作真漂亮。欣赏亚伦老师好帖{:4_187:}

在播放器上还加了个小按钮呢，这个漂亮。构思很巧妙{:4_199:}
