Another article re CD sales

Yet, another interesting article re the decline of CD sales and popularity of downloading singles. The article raises an interesting parallel that I had not really considered, i.e. that artists/record companies are returning to the single as the primary medium for sales, such as in the 50's/60's when artists primary sold 45's with an A & B side as opposed to full length albums. I suppose its true that history does repeat itself.
