Piracy is the greatest threat facing the music industry worldwide today. This study developed and empirically tested a model examining the antecedents of consumer attitude and behavioral intention toward music piracy behavior. Two types of music piracy behavior, unauthorized duplication/download and pirated music product purchasing, were examined. Based on a field survey in Taiwan, the results showed that attributive satisfaction, perceived prosecution risk, magnitude of consequence, and social consensus are very important in influencing customers' attitude and behavioral intention toward two types of music piracy behavior. In addition, singer/band idolization can affect the attitude and behavioral intention in the case of pirated music product purchasing. Perceived proximity was found to affect the attitude and behavioral intention in the case of pirated music product purchasing. However, it only influenced behavioral intention in the case of unauthorized duplication/download.
