In theory, tiered pricing could mean that songs change from 99 cents to at least 99 cents, that they change to at most 99 cents, or that they continue to average 99 cents over all sales.
Someone else in the thread said that having tiered or otherwise variable pricing is an invitation to start being greedy. Perhaps songs will still average 99 cents to start, but slowly you'll see that go to $1.09, $1.19, etc. To some extent that's expected due to inflation, but I fear (as many do) that the industry will start taking advantage.
Look at the variable-pricing structure of gas prices. You can't tell me that the ACTUAL COST of gas varies and jumps as much as the prices do at the pumps, particularly considering the long time it takes for a purchase of raw crude to become gasoline.
Compare that, with, say, a dollar store, where everything in the store is (ostensibly) priced at $1. Some items are cheaper and you get 2/$1 or 3/$1. Unfortunately I've been seeing more dollar stores that get a little liberal with the name and I've seen items for $3, $5, even $20 (!) - and at that point I feel you can't really call it a dollar store anymore.
As someone says, if I go see "Serenity" tonight or if I choose to see a turd, I pay the same $10 for the movie ticket. If I rent a movie at Blockbuster I pay the same $4.99 whether it's Ishtar or Lord of the Rings.
Actually, I can provide counter-example by pointing out that at Blockbuster, you pay more for new-release rentals than for the older ones -- perhaps that model would be a compromise. A two-tier, fixed-price model, where say new releases are $1.29 and older songs are $.59 or $.79. But that still opens it up to price-increase-creep (there's something aesthetic about 99 cents), and open to abuse by calling Backstreet Boys a "new release", etc.
