I Want It That Way (Max Martin/Andreas Carlsson)

I Want It That Way (Max Martin/Andreas Carlsson)
Yeah
You are
my fire
The one
desire
Believe
when I say
I want it that way
But we
are two worlds apart
Can't reach to
your heart
When you say
I want it that way
Tell me why
(Ain't nothin' but a heartache)
Tell me why
(Ain't nothin' but a mistake)
(Tell me why)
I never wanna hear you say
I want it that way
Am I
your fire
Your one
desire
Guess I know
it's too late
But I want it that way
Tell me why
(Ain't nothin' but a heartache)
Tell me why
(Ain't nothin' but a mistake)
(Tell me why)
I never wanna hear you say
I want it that way
Now I can see that we've fallen apart
From the way that it used to be, yeah
No matter the distance
I want you to know
that Deep down inside of me
You are
my fire
The one
desire
(You are, you are, you are, you are)
Don't wanna hear you say, hey
Ain't nothin' but a heartache (hey, heh, yeah)
Ain't nothin' but a mistake (don't wanna hear you say)
I never wanna hear you say (oh yeah)
I want it that way
Tell me why
(Ain't nothin' but a heartache)
Tell me why
(Ain't nothin' but a mistake)
(Tell me why)
I never wanna hear you say
(Don't wanna hear you say)
I want it that way
Tell me why
(Ain't nothin' but a heartache)
(Ain't nothin' but a mistake)
Tell me why I never wanna hear you say (hear you say, yeah)
I want it that way
Cause I want it that way
中的Ain't nothin' but a heartache
什么意思?Ain't nothin'怎么理解?

There are not nothing but a heartache.双重否定,其实就是否定：There are nothing but a heartache.除了心疼再没别的了.Ain't 是 are not 的缩写.
喜欢后街唱的这首歌.
