Ever read the lyrics to "Safe in the arms of love" from Martika's Kitchen album?
They have many similarities to Prince's "Open Book". Now, while Prince contributed quite a few songs to that album, he doesn't appear to have been involved with this song..

Safe in the arms of love

You say my heart's an open book
there are pages of my life you've never seen
you've always been there between the lines
but, there's so much more you just can't seem to read

peices of dreams
pull us our separate ways
but we'll return someday

so let the wind blow
'cause my heart knows
we were meant to be together, from the start
when the sars shine bover one sky
i'll be safe in your arms of love

you take me to another world
it feels so natural, so right
then we awaken to reality
'cause we both know that now is not the time
under your spell
i'll nbever be all that i can,
but i'll come back again

so let the wind blow, 'cause my heart knows
we were meant to be together from the start
when the stars shine over one sky
I'll have faith
I'll be safe in the arms of love

I'll have faith
what's mine is mine
and no one can take that away from me
I believe that in the end
we'll never have to be apart again.

I've always wondered about this. I suspect they wrote it sort of together...who knos.
