Lyrics:

Jamie Foxx
You stayed awake half the night
Love is
Put you through changes
Tell me why, tell me why, tell me why
It must be love that's on your mind
You doin' things, you wouldn't before
And you oughta know

Mary J. Blige
Love will make you oh so happy
Inside

Jamie Foxx
Can't control it but it takes you over

Mary J. Blige
Love will make you oh so sad
Make you cry

Both
Changes

Mary J. Blige
Love changes, Love changes

Both
That's what love puts you through

Mary J. Blige
Love changes, Love changes

Both
Changes

Mary J. Blige
That's what love makes one do
Love changes

Mary J. Blige
Wonderin' if it's real this time
Just not another half-goodbye
You walk around starry eyed
Can't believe that love would hurt again
Hurt again

Both
I can't believe that this love will

Both
Love will make you oh so happy
Inside

Jamie Foxx
Can't control it but it just takes you over

Mary J. Blige
Love will make you oh so sad
Make you cry

Mary J. Blige
Changes
Love changes, Love changes
That's what love puts you through
Love changes, Love changes
Changes
That's what love makes one do
Love changes

Mary J. Blige
Changes
Love changes, Love changes

Love will make you oh so sad make you cry
Love will make you oh so happy inside
