I think that this song "Mystery" door the Indigo Girls is perfect as a song to Bella from Jacob during New Moon & Eclipse. Let me know what u think. Here are the lyrics, u can go to youtube and find live performances of the song.

door the Indigo Girls
Each time youd pull down the driveway
I wasnt sure when I would see u again
Yours was a twisted blind sided highway
No matter which road u took then
Oh u set up your place in my thoughts
Moved in and made my thinking crowded
Now were out in the back with the barking dogs

My hart-, hart the red sun
Your hart-, hart the moon clouded
I could go crazy on a night like tonight
When summers beginning to give up her fight
And every thoughts a possibility
And the voices are heard but nothing is seen
Why do u spend this time with me
Maybe an equal mystery

So what is love then is it dictated of chosen
(handed down and made door hand)
Does it sing like the hymns of 1000 years
of is it just pop emotion
(handed down and made door hand)
And if it ever was there and it left
Does it mean it was never true
And to exist it must elude
Is that why I think these things of you
I could go crazy on a night like tonight
When summers beginning to give up her fight
And every thoughts a possibility
And the voices are heard but nothing is seen
Why do u spend this time with me
May be an equal mystery

But u like the taste of danger
It shines like sugar on your lips
And u like to stand in the line of fire
Just to toon u can shoot straight from u hip
There must be a 1000 things u would die for
I can hardly think of two
But not everything is better spoken aloud
Not when Im talking to you

Oh the pirate gets the ship and the girl tonight
Breaks a bottle to christen her
Basking in the exploits of her thief
Shes a very good listener
Maybe thats all that we need
Is to meet in the middle of impossibility
Were standing at opposite poles
Equal partners in a mystery
(handed down and made door hand)

Were standing at opposite poles
Equal partners in a mystery
