Chords(Intro/Chorus/Rap) - C F C G Am F C G

[Nelly Furtado]
C                     F
 I don't wanna be left
                   C
In this war tonight
                         G
Am I alone in this fight?
                   Am
Is anybody out there?
                   F                        C
Don't wanna be left left in this world behind
                        G
Say you'll run to my side

[K'naan]
C
Something 'bout mary
Never won a pageant
F
Never felt pretty
Never looked like cameron
C
Diaz was her last name
Always been abandoned
G
Keep your head up
Baby girl this is your anthem
Am
There goes hannah
Showin' off her banner
F
Rocking that crown
Make them boys go bananas
C
When you're insecure about yourself
It's a fact
G
You can point a finger
But there's three pointing back
C
I can see her crying out, yeah
F
Is there anybody out there?
C
She's really counting on your love
                    G
Still struggling uphill

But you act like you don't care
Am
Right now she could really use a shoulder
F
Hanging onto the edge til it's over
C
She's crying for your love tonight
G
Loneliest heart to survive, she said

Same for chorus and 2nd rapping verse. ^
