Fond Father,Not knowing your daughter's experience with point of sale marketing, and having only consumer experience of my own, I wonder: With the right cover art and a good position by the checkouts, a tone-deaf, laryngitic accordion player would sell. It seems to me that the only role of content selection is to sell it to the purchasing department.
Sincerely, Cynical about mass marketing folk music, but delighted for any obscure musician who'll rake in royalties if it flies.
