Piracy Boosts CD Sales?

According to a research funded by Industry Canada, P2P downloaders buy more CDs.

There are two comments about the research I really like.

Why does it have to be that downloading INCREASES music sales, and not just:

People who download music LIKE MUSIC, and therefore are prone to buy more in general regardless of torrents.

Why does downloading and buying have to be directly linked in the behaviours of my mind, they are cousins (similar trends) and not twins (where one only gains if the other looses).

and

These statistics do not apply to me. Ever since I began file sharing, I have stopped buying cds. I support the artists by going to concerts and buying merchandise.

Besides, most of the artists I listen to are dead. If I bought their CD, I wouldn’t be supporting the artist. My money would go strait to the record executives, and I see no point in doing that.
