I don't think it's meant to be a logical deduction (it's *two separate*
sentences), just statement of some facts.
That said, saying that sales would have declined anyway even if hundereds of
millions of teenagers were not pirating music over the internet is, well,
nonsense. Did piracy reduce sales? Sure. Was piracy avoidable in the
Internet age? No, not with the current structure of the internet anyway. It
seems inevitable to me that things will have to change, for better or worse.

I can play a large section of Bach's Toccata and Fuge in D minor from
memory, if that makes it any better?

Asymmetric encryption. I can see how that would work. (OTOH, couldn't
you just modify the firmware to not require this?)

I see two possibilities.
1. There is one secret decryption key. Every iPod (or whatever) has this
key burned inside it, with tamper-proof hardware to stop you getting at
it. In this case, you don't *need* to decrypt the data; you can just
copy the encrypted files and they will play perfectly on any iPod. So
this is clearly a non-solution.
2. There is a unique key inside every iPod. That means that music which
you have legally purchased can only ever be played on 1 device. So this
is clearly also a non-solution.
I'm not seeing a way this can be made to work properly...

You mean you wouldn't know who of them is the composer if you listen to
a song, or that you have never heard those names? :)

Oh, I've obviously *heard* of them. (I have actually had my surname
confused with one of them - as if!) But I would have no idea what they
sound like. Or which millenium they lived in. Or which country. Or...
anything, really.

But it has been done, and it works, so how about doing some research?

I was expecting you to like Bach. He's the most mathematician-like of the
classic composers. But as usual, I'm impressed by your amazing ignorance about
well-known facts.
"I wouldn't recognise any of the others", the other being Beethoven and Mozart.
Come on! Even the chinese behind the Great Wall know Beethoven and Mozart!!

Right. So the decryption key is stored seperately from the actual file.
Thus, all you have to do is figure out how to copy the decryption key as
well and you can copy the data to as many million iPods as you want. QED.

Knowing what a tune sounds like is a "fact", is it?

Sure, I've heard of them. But I have no idea what they sound like. You
make it sound like a crime or something. :-P

Maybe technically you could see it like that, but most people will see
a "because" between the two sentences, and I'm quite sure the writer more
or less implied that.

Nobody denies that music piracy happens. However, proving that music
piracy is the reason for decreased sales is quite much harder.
If I'm not mistaken, something similar has happened before: Radio stations
started broadcasting music, and some time after music sales dropped quite
a lot. Of course the music industry, even today, likes to make a correlation.
What they don't like to mention is that this drop happened after 1929,
which is a much more likely explanation for the decreased sales.
