Re: Yes and no.
"But there's no real scarcity in digital storage. Online purveyors of artistic content need keep only one copy of each item, because it's copied rather than removed when sold. They can use sales records to determine the popularity of a song, but lack of scarcity and remnants of the flattened-value mode mean they generally don't use this to change the price. Price difference online becomes primarily a reflection of the novelty of the content"
Looking at iTunes, there is variability in pricing (new popular songs costing more than the average price) which probably reflects the price of promotion and the 'novelty factor'.
The problem with a bit locker like iTunes or similar is that people can't really deal with nearly infinite number of songs or apps on the shelf. I have experienced going to buy a song and finding 20+ versions of it - the remixes, covers, live versions, remastered, album vs single, censored radio release / non-censored extended etc. Something I have heard described as the 'Tyranny of Choice'
Ultimately the most significant cost of music, apps, even movies appears to not in creation, storage or distribution but simply making people aware of it. Some random Icelandic band might have just created the best album of all time that I will love and be very willing to pay full price for, but if I am never made aware of it I will never hand over my money. And to make a jaded world-wide population aware of some artistic creation that is bombarded daily with vast amounts of advertising is getting increasingly difficult.
I remember Snow Crash from 20+ years ago discussing the problem; in a VR world, land is infinite but like the real world, some land in inner cities is worth more than the same amount of land in some Mongolian desert.
In the iTunes world, having the Album cover on the front page or in a top 10 list must be worth vastly more than having it simply sitting in the iTunes catalogue.
