Price of one box of Kashi cereal: $5.00
Price of one entire album on Amazon: $5.00
Digital music, with no packaging/warehouse/storage/transportation costs, should be less expensive than music in vinyl or compact disc form.
But, it seems incongruous to charge only $5.00 for an album of 12-13 songs which can be listened to over and over again and shared with a theoretically infinite number of people.
The box of cereal is gone very quickly, but the songs remain.
