My Sweet King ...

I don't know if you've already heard, but this is certainly news to me. Two days nakaraan my sister and I (who are both huge MJ fans) were messing around on the internet. And then this screen came up:
Michael Jackson Is Alive - Secret Message In This Is It
I was confused. I didn't understand. Then in some comments it read, "Use the music programme Audacity to play This Is It reversed and you will hear the message". So we did so. And this is what we found:

And I'm just the one in it all
Who is laughing?
Who is laughing?
I hope you are
And I'm not dead
They wanna believe
That I live on and
I'm just the one...
