LYRICS (Source is Barbie Movies Wikia):

Astra Rhoid/Barbie's Mom

When you don't know where to go
And you're feeling all alone
Look inside yourself
You're so much more than you know
When you're stuck and out of time
You can cross the finish line
You're a champion
You'll always be a winner

Oh, oh, oh
Oh, oh
Oh, whoa

You can be anything you want
If you believe in who you are
You'll light up the whole world
You're shining so bright
Anything is possible
When you look into your heart
Oh, oh, oh, oh
You're a shooting star

Barbie Rhoid:
When I'm down and feeling scared
I know I should take a chance
The world is sitting right here
In the palm of my hands
I'm flying higher than before
And giving up is not a choice
I'll push the doubt aside
And step into the spotlight

Oh, oh, oh (AR: ohhhh)
Oh, oh (AR: ohhhhh)
Oh (AR: ohhhhh ah)

I can be anything I dream
Live the life that's made for me
I'll light up the whole world
I'll be shining so bright
Anything is possible
When I look into my heart
Oh, oh, oh

I can be anything I dream (AR: you can be anything...)
Live the life that's made for me (AR: if you just believe)
I'll light up the whole world (AR: oooohhhhh)
I'll be shining so bright (AR: you're shining bright)
Anything is possible
When I look into my heart
Oh, oh, oh
I'm a shooting star (AR : Ahhhhhhhh)

Oh, oh
I'm a shooting star (AR : Ahhhhhhhh)
Oh, oh

I'm a shooting star (AR: you're my shooting star)
