Something I listened too and really liked it.. The karaoke I found seems a lot softer than the original.. But I don't mind! 8D
This here is a try out, since well.. I only JUST starting to learn it, and now I got the first few lines ^.^;;;

---

They're not gonna keep me down
They're not gonna shut me out
They're gonna do what they do, I'll do me
I'm moving against the crowd
I'm drowning out, their doubt
They're gonna do what they do
I'll do something original,
Be unforgettable
They're gonna know my name

CHORUS:

(One day) I'll make you a believer
(One day) I got this all I need is
(One day) Don't try and tell me I can't
(And now) I'm writing the future
(Watch out) Cant stop I'm a mover
(One day) You're gonna know who I am...
I will fly high and free
It's my fate wait and see
One day.
