《Goodnight Baby》的歌詞如下：
Goodnight my angel
Sleep tight my baby
You don't need to worry
You know that I am here
Just close your eyes and let yourself be free
You don't have to be alone
I'll be here forever
Goodnight my angel
Sweet dreams my baby
I love you forever
As long as forever's day
And when tomorrow comes
I'll be right here
With you in my heart and my mind
Sleep tight my angel
Goodnight my love
I'll always remember
Every smile and every tear
Until we meet again
My angel goodnight
Baby~
Baby~
Baby~
My angel
My love
