Here We Go Again歌词：
I throw all of your stuff away
丢掉你所有的物品
Then I clear you out of my head
清除所有你的回忆
I tear you out of my heart, and ignore all your messages
把你从我心里抹去，忽略你的每条短信
I tell everyone we are through
我告诉每个人我们分手了
Cause I’m so much better without you
没有你，我会变得更好
But it’s just another pretty lie cause I break down
但这只是一个美丽的谎言，因为我已崩溃
Everytime you come around
每次你来我身边
So how do you get here under my skin？
你是怎样一点点占据我的内心
I swore that I’d never let you back in
我发誓我绝不要你回到我身边
Should have known better in trying to let you go,
应该尽力尝试着让你离开
Cause here we go, go, go again
因为我们又和好如初
Hard as I try, I know I can’t quit
我已尽全力，可是我不能放弃
Something about you is so addictive
你是如此迷人
We’re falling together
我们一同摔倒
You’d think that by now I’d know
你觉得，现在我知道了
Cause here we go, go, go again
可是我们又和好如初
You never know what you want
你从不知自己想要什么
And you never say what you mean
也总是口是心非
But I start to go insane everytime that you look at me、
可我每次一见到你就像疯了般
You only hear half of what I say
你只听了我说的一半的话
And you’re always showing up too late
而且总是迟到
And I know that I should say goodbye, but it’s no use
我知道我该说再见了，但这根本没用
Can’t feel with or without you
没有了你，一起都毫无生气
Oh Oh
哦哦
So how do you get here under my skin？
你是怎样一点点占据我的内心
I swore that I’d never let you back in
我发誓我绝不要你回到我身边
Should have known better in trying to let you go,
尝试着让你离开
Cause here we go, go, go again
可是，我们又和好如初
Hard as I try, I know I can’t quit
我已尽全力，可是我不能放弃
Something about you is so addictive
你是如此迷人
We’re falling together
我们一同摔倒
You’d think that by now I’d know
你会觉得，现在我知道
Cause here we go, go, go again
可是我们又和好如初
Again, and again and again and again and again
一次又一次，和好如初，重新来过
I throw all of your stuff away
丢掉你所有的物品
Then I clear you out of my head
清除所有你的回忆
I tear you out of my heart
把你从我心里抹去
Oh Oh (Oh Oh)
哦哦，哦哦
