Abstract During the last years music sales had sharply declined. According to the recording industry, one of the reasons for this decline is the development of peer-to-peer (P2P) networks. The main goal of this research was to establish a relationship between consumer attitudes and the P2P music consumption proportion. We identified a set of characteristics of P2P networks that could explain the proportion of P2P music compared to Compact Disc (CD) music and we observed on a sample of 4060 Spanish P2P users the impact each of those characteristics had on the CD-purchasing behaviour of these users. Results show how price, assortment and discovery of the P2P music consumption process were related to higher proportions of P2P music.
