[Verse 1: OneRepublic]
For those days we felt like a mistake
Those times when love's what you hate
Somehow, we keep marchin' on
For those nights when I couldn't be there
I've made it harder to know that you know
That somehow, we'll keep moving on

[Chorus: OneRepublic]
There's so many wars we've fought
There's so many things we're not
But with what we have, I promise you that
We're marching on, we're marching on, we're marching on
There's so many wars we've fought
There's so many things we're not
But with what we have, I promise you that
We're marching on, we're marching on, we're marching on

[Verse 2: Timbaland]
So many hills we had to climb
Almost without our strength
But we kept... slowly marching on
Time heals the wounds we couldn't close
Blood sweat and tears dried up
We're okay, we kept marching on

[Chorus: OneRepublic]
There's so many wars we've fought
There's so many things we're not
But with what we have, I promise you that
We're marching on, we're marching on, we're marching on
There's so many wars we've fought
There's so many things we're not
But with what we have, I promise you that
We're marching on, we're marching on, we're marching on

[Verse 3: Timbaland]
Get your legs and walk because we're not too far
A little more to go, but well we marching on
Ah, well, we marching on, ah, well, we marching on
Ah, well, we marching on, ah, well, we marching on
If we lose the sun, we turn the night back
Yep, we going to win, we got to fight back
We marching on, ah well we marching on
Ah well we marching on, ah well we marching

[Bridge: OneRepublic]
The bridges are gone, and we're almost home
The end is clo-ose

[Chorus: OneRepublic]
There's so many wars we've fought
There's so many things we're not
But with what we have, I promise you that
We're marching on, we're marching on, we're marching on
There's so many wars we've fought
There's so many things we're not
But with what we have, I promise you that
We're marching on, we're marching on, we're marching on

Timbaland

Timbaland (born Timothy Zachery Mosley on March 10, 1972) is a record producer and songwriter, and occasionally does some rapping on the side.

His first full-credit production work was in 1996 on Ginuwine…the Bachelor for R&B singer Ginuwine. After further work on Aaliyah’s 1996 album One in a Million and Missy Elliott’s 1997 album Supa Dupa Fly, Timbaland became a prominent producer for R&B and hip-hop artists.

He initially released several albums under his own name (along with his fellow collaborator Magoo), and eventually developed a solo career as a producer.
