I'm not much for putting up song lyrics all over the place, but I love Smokey Robinson songs:

I Heard it Through the Grapevine
(written by Whitfield/Strong, originally released by Smokey Robinson & the Miracles, made famous by Marvin Gaye)

Oo, I bet you wonder how I knew
'bout your plans to make me blue
with some other guy you knew before
between the two of us guys, you know I love you more
it took me by surprise
when I found out yesterday

Don't you know I heard it through the grapevine?
Not much longer would you be mine.
Oh, I heard it thought the grapevine -
and I'm just about to lose my mind

I know a man ain't supposed to cry
but these tears I can't hold inside
losing you would end my life you see
because you mean that much to me
you could have told me yourself
that you loved someone else

Instead, I heard it through the grapevine.
Not much longer would you be mine.
Oh, I heard it through the grapevine, and I'm just about to lose my mind.

People say believe half of what you see
Son, and none of what you hear
But I can't help but being confused
If it's true, please tell me, dear
Do you plan to let me go for the other guy you loved before?

Don't you know I heard it through the grapevine
Not much longer would you be mine.
Oh, I heard it through the grapevine, and I'm just about to lose my mind.
