冷若冰霜 - 耳朵听了会怀孕
There she stands on the floor
Colder than ice
Vision fixed on the door
Colder than ice
Now she knows that she's nice
Golden hair and deep blue eyes
No-one dances her twice
Nothing happen so far
'Cause who wants to get burned by the ice
No one reach her tonight
Before she takes flight
She's colder than ice
How can I get in first
Hurt to entice
She's colder than ice
Colder than ice
Colder than ice
Colder than ice
Suddenly I was there
And she's is in his arms
Holds her close to him
And she feels his charms
Couldn't see it no more
Could it be I'm loosing for sure
Oh it's breaking me up
'Cause I'm the only one
Who dares to walk on the ice
No one reach her tonight
Before she takes flight
She's colder than ice
How can I get in first
Hurt to entice
She's colder than ice
No one reach her tonight
Before she takes flight
She's colder than ice
How can I get in first
Hurt to entice
She's colder than ice
Colder than ice`;

这个评分后就变成一张不动的图片了呢，只有刷新了才会变成视频背景{:4_173:}
