Hey, you're you, the one who found my MP3! So what did you want to tell me?
1) Blake from the subway station of Kerning Square is trying to... (You explain the situation.) So now he needs a new song for his debut concert. Would you compose one for him?

Compose... Ah, ha ha! I don't know if you know this, but I'm kind of a big deal. I'm a famous and respected composer. The fee for my music is hefty. You came prepared to pay, didn't you?

Tell you what, I'll compose one song, free of charge, if you bring me 50 Fancy Amplifier Cables from the 7th-8th floor of Kerning Square. I really want those cables.

But I can't just give you a song for free. Think about what it would do to my reputation!

You have what I want? Now we're talking.

One, two, three... You brought all the cables I wanted. Okay, here it is. As promised, here are my Composition Notes with a new hit song. (He seems reluctant to let go of his Composition Notes.)

Did you forget that a song from me is worth at least 50 Fancy Amplifier Cables? Please bring them from the 7th-8th floor of Kerning Square.
