Physical Singles Sales
A true 21st century singer, Demi sold irrelevant numbers of physical singles. Her breakthrough hit This Is Me was already a digital only single. A few of her songs like We Rock and La La Land had a CD release which remained highly limited (realistically restricted to 1,000 to 3,000 units per single) and thus never charting in national rankings. As it is impossible to specifically identify sales of individual CDs in that context, a total figure of 20,000 units will be assigned to the Orphan Album category.
