..was at the end of the YouTube URL deciphered be the clever ArkhamCity.co.uk but here is the Riddler Audio Clue:

Below is the Penguin Audio File transcribed:

Penguin: Strange, don’t think you’ve beaten me.
Strange: I just thought we could both benefit from a little talk, Mr. Cobblepot.
Penguin: Don’t try that psycho mumbo-jumbo with me, Strange. I’m not like the other crazies.
Strange: Of course not. After all, considering the… challenges you’ve faced.
Penguin: Challenges!? What freakin’ Challenges!? You’re not better than me. No one is. I own this place.
Strange: Well, to be clear, I allow you certain freedoms, but let’s continue. Why do you feel the need to own anything? I believe it is a mechanism to compensate for some childhood inadequacy. You were friends with the Waynes, correct?
Penguin: I was. Til someone did the world a favour and blew the brains out of little Wayne’s self-righteous parents. I was laughing for weeks. It still brings a smile to my face.
Strange: And you think that’s ok?
Penguin: Ok? No I don’t think it’s ok… I think it’s bloody hysterical. Hahahaha! That family destroyed mine. What happened to them, well, it couldn’t have happened to nicer people.
Strange: Take a seat Mr. Cobblepot.
Penguin: Wait now, Strange.
Strange: I wanted to talk about your apparent hatred of the Waynes. Your outburst last time was most interesting.
Penguin: It’s simple really, I don’t like the sneaky little bastards. Looking all high and mighty cause someone killed mummy and daddy.
Strange: Most people look upon him with sympathy.
Penguin: No they don’t, they’re jealous. Jealous of his money, his cars, his women. He lost me sympathy when he vanished from the city. I can’t tell you how much I hope he’s visiting his dear mum and dad.
Strange: Where do you suppose he went?
Penguin: How am I supposed to know?
Strange: Let us move on, then.
Penguin: No. It’s time that you do something for me.
Strange: And what is that?
Penguin: Here’s a list.
