'Want wewe Gone' is the ending theme for Portal 2 and I think it really suits Shadow and who he is. Anyway, wewe should check it out on YouTube au something.

"Well, here we are again
It's always such a pleasure
Remember when wewe tried to kill me twice?
Oh, how we laughed and laughed
Except I wasn't laughing
Under the circumstances I've been shockingly nice

wewe want your freedom, take it
That's what I'm counting on
I used to want wewe dead but
Now I only want wewe gone

She was a lot like you
(Maybe not quite as heavy)
Now little Caroline is in here too
One siku they woke me up
So I can live forever
It's such a shame the same will never happen to you

You've got your short, sad life ahead
That's what I'm counting on
I'll let wewe get right to it
Now I only want wewe gone

Goodbye, my only friend
Oh, did wewe think I meant you?
That would be funny if it weren't so sad
Well wewe have been replaced
I don't need anyone now
When I futa wewe maybe I'll stop feeling so bad

Go make some new disaster
That's what I'm counting on
You're someone else's problem
Now I only want wewe gone
Now I only want wewe gone
Now I only want wewe gone
Now I only want wewe gone"
