How did you get that URL?
+1 on this question for FableOfTheBees
Not to be rude, but it's not nice not explaining how a crucial new step is uncovered. What's the reasoning behind finding "adooradooradooradoor.php"?
Sorry...it was much simpler than what I posted previously, and why I provided a bad solution..
Turns out that the reason "star.mp3" worked is because I was connected via TOR. Any password works when you access
http://whit3r4bbi7.com/onedoorclosesanotherdooropens/ via TOR network. Makes sense now...

You should see this in your Tor browser when you connect.
Fable, not asking about "star.mp3", the question was how on earth did you get "adooradooradooradoor.php"?
