Can't Stop Me Now!

I went and watched Alice in Wonderland on Monday and I really do love the the movie and this song performed by Avril Lavigne. Also since I have watched the movie it has got me asking the question...Why is a raven like a writing desk?
Alice Lyrics

Trippin out
Spinning around
I'm underground
I fell down
Yeah I fell down

I'm freaking out, where am I now?
Upside down and I can't stop it now
Can't stop me now, oh oh

I,I, I'll get by
I,I, I'll survive
When the world's crashing down
When I fall and hit the ground
I will turn myself around
Don't you try to stop me
I,I, I won't cry

I found myself in Wonderland
Got back on my feet, again
Is this real?
Is this pretend?
I'll take a stand until the end

I,I, I'll get by
I,I, I'll survive
When the world's crashing down
When I fall and hit the ground
I will turn myself around
Don't you try to stop me
I,I, I won't cry
