Is this a test of a new business model for iTunes, a way to counter the streaming services? Make deals with individual bands for their latest album and then push it out to all accounts automatically. The only potential problem with that idea is humorously expressed in the above Douglas Adams quote.
It's hard for overseas people to put those numbers in context, because we don't know what a normal income is in Hong Kong. But if you say people are willing to pay twice as much then I think Apple should probably put the price up.
They could have just put it on iTunes as a free album, that is, the purchase button says "Free" but until you click it, you don't get it. And a nice big ad front and centre so everyone knows. Making everyone automatically purchase it is going a bit far.
