后街男孩第八张录音专辑《 In a World Like This》中的一支单曲，该专辑于 7.30全球发行，而《 Permanent Stain》是最早曝光的一首新歌。由 BSB亲自操刀完成。一首经典的 BSB式情歌。

这首歌的曲风欢乐，但是其中却也带有一丝淡淡的离伤。

歌词赏析：

Out of the rain, looking for sunshine

I call your name, but you are like a ghost

I let you disappear, should've never let you go

I want to say just for the record

That you still got my heart and my soul

You know were worlds apart, yeah

I've got to let you know

You are the piece I can't replace, oh

You left a mark that won't erase,

one else can teach me how to love again

Cause you left a permanent stain on my heart and

I've been feeling it

Never mind what people say cause they don't understand

How you left a permanent stain on my heart and I've been feeling it

Some try to break through the walls

Built up but they don't compare to you

One chance, I swear

I'll never let you go

You are the piece

I cant replace, oh

You left a mark that wont erase, no

No one else can teach me how to love again

Cause you left a permanent stain on my heart and I've been feeling it

Never mind what people say cause they don't understand

How you left a permanent stain on my heart and I've been feeling it

Ooh ooh ooh ooh

You left a permanent stain on my heart and I've been feeling it

One should with time

Never gonna fade, one can touch the flame and tame the fire

You are the piece I can't replace, oh

You left a mark that won't erase, no

No one else can teach me how to love again

Cause you left a permanent stain on my heart and I've been feeling it

Never mind what people say cause they don't understand

How you left a permanent stain on my heart and I've been feeling it

Ooh ooh ooh ooh

You left a permanent stain on my heart and I've been feeling it

Ooh ooh ooh ooh

You left a permanent stain on my heart and I've been feeling it
