This is not the real conclusion to my economics term paper

Ultimately, this is how I see it: a pint of decent draft beer in Montreal starts at around six Canadian dollars (tip, pre-tax). If you bumped into Thom Yorke in a bar, would you be moved to buy him a pint? If yes, then the Radiohead album is worth your six bucks. Or you could get a round for the whole band etc. but the point is it's a much more wholesome way of framing the problem than in terms of corporate percentages or information's "need" to be "free". Unless you're buying drinks for Britney this week which I don't really recommend, maybe a nice fruit smoothie or something.

(Apparently the average Radiohead album downloader tipped four pounds, which I'm reasonably certain is what a pint costs in London. Now to crystallize theory into equation format.)
