歌詞: Danity Kane. Welcome To The Dollhouse. Key To My Heart.

Someone took the key to your heart
Someone took the key to your

Could've swore, I had it right here with me
Susy told me, no one else could take it away
Maybe I misplaced it, checking where it could be
But I'm running out of possibilities

See now, me and him are having all these problems
Retrace my steps to see if I caused them
There's something he's keeping from me
What could it be? Oh

Please don't tell me, someone took the key to your heart
Right from the bottom, it tearing us apart
How could you just let anyone in?
How could you do it, baby? Into your heart

Kinda chilly out here on the other side
When did I turn my back long enough for her to take my place
Must of been a mix up showing in the same mistake
But if not when I see her they might lock me away

'Cause now, me and him are having all these problems
And it don't take a genius to try and solve them
There's someone he's keeping from me
Oh, who could she be? Oh

Please don't tell me, someone took the key to your heart
I can't take it
Right from the bottom it tearing us apart
How could you just let anyone in?
(Don't you let them in, no)
Into your heart

I've called it in, I made my plan
I hope they find it right away
The missing piece means everything
What else could it be?

Please don't tell me, someone took the key to your heart
Right from the bottom, it tearing us apart
Just let anyone in?
Into your heart
