Ratings in Social Music Cataloging Services

A general survey of social software is presented with a focus in social music cataloging services. Two example systems review and rating functionality are compared in detail. We observed a case of distorted product ratings, where overactive fan base promoted a single album at the expense of others. Despite the potential for unfair ratings, social cataloging systems are a promising form of participatory media, challenging and complementing traditional, professional reviews used in print media. Some suggestions are provided to issue the reliability and fairness of individual reviews.
