I know that pop music is iTunes' best seller, but it's not the only thing they sell. I buy audiobooks, opera, and symphonies, which tend to be more expensive and less easily divided into neat three minute Clear-Channel chunks.
That's true. Per-song pricing is just the best of poor options. Paying per-minute or any such alternative would make the store more confusing, and it's the simplicity of the store and it's pricing structure that's a key reason for it's growth.
