Lyrics:

I told this heart of mine our love could never be,
But then I hear your voice, and something stirs inside of me
Somehow I can't dismiss the memory of your kiss,
Guess my heart has a mind of its own

No matter what I do, no matter what I say
No matter how I try, I just can't turn the other way
When I'm with someone new, I always think of you,
Guess my heart has a mind of its own

You're not in love with me, so why can't I forget?
I'm just your 'used-to-be'; it's wrong, and yet...

I know forgetting you would be a hopeless thing,
For I'm a puppet and I just can't seem to break the string
I say 'I'll let you go,' but then my heart says 'no'
Guess my heart has a mine of its own
Guess my heart has a mind of its own
