Technology moves so incredibly fast that this concept may not have any real legs, but I like the idea of purchasing at least some of my music this way. It sounds as though the UK is acting upon slumping music sales, but I have read some conflicting information regarding the pricing. An article from the Times Online claims Universal will be charging more for such USB singles (nearly 5 pounds!) and the first article I referenced had a much more practical price schema; projecting albums for 4.99.
Granted, when you calculate the exchange rate, it wouldn’t be as alluring.
The other interesting point is that sales of the USBs will officially count in chart calculations. Wow, it would take maybe a year’s worth of trial efforts before you’d get Billboard to agree to something so new and innovative!
