zqansen：你好！

这首歌我听过：《爱是怀疑》

rap：

It's like sometimes I don't even know who I am anymore

有时我似乎连自己都认不出来了（或 不能自已）

Can't see what's the point of being in love anymore

不知爱情的意义何在

It's a game what a shame

遗憾这不过是一场游戏

You make it lame by going insane about it

你的疯狂使得这段爱情匮乏无力（或 支离破碎）

This love ain't what you say about it

爱情不是说说就算的

It's about what you do about it

关键在于行动

So get with it, stick with it

所以坚持住 忍耐住

If you still can't understand well,

如果你依然不懂的话

then forget about it

那就忘了它吧

Sometimes all you do to me is sulk,

有时你的所作所为只会惹我生气

like you got something to say

有时你似乎有话要说

But nothing makes sense when you move your lips

可一开口就变成了无理取闹

All you do is get pissed at me

你只会冲着我发脾气

Dissed at me

这样对我嗤之以鼻（或 诋毁我）

Wonder why you're still here with me

我一颗蠢蠢的心，只想明白我为何还和你在一起

大部分都是我意译的

再见，祝好！
