A band-member-backtracking application called BandNavi has been developed that enables a user to discover new songs and bands by tracing musicians who have played in different bands.Previous similarity-based song recommendation systems only retrieve similar songs, but many retrieved results are not songs by musicians the user likes.By using a web-mining technique, data was collected on member history information of 3000 bands BandNavi enables a user to discover other bands in which a musician has played.BandNavi was implemented on the iPhone, and experimental results show that 70 percent of subjects understood how to use BandNavi within five minutes, 70 percent enjoyed tracing the bands and their members’ connections, and 52 percent discovered a previously unknown band that they liked.
