A fanzine writer once observed that sometimes a copy of a copy can be better than the original. But when it comes to pop music, where originality is about as prized as diversity, the real question is whether a copy of a copy can sell better than the original (or its copy). Certainly, to look at the progression from the Lawrence Welk Hotsy-Totsy Boys to the Bee Gees to Hanson is to understand that quality doesn’t vary much in aural ready-mades. Quantity of sales, however, does:
