Purpose: Two facts are established: Firstly, social influence makes success in cultural markets unpredictable and unequal. Secondly, aesthetic quality of songs is a significant factor of influence on popular appeal of songs. My study connects these two areas of research, investigating in how far experts’ judgements and popularity of songs are used (a) as signals of aesthetic quality in music markets, (b) in how far this influences demand for certain songs and (c) in how far training in aesthetic appreciation changes how experts’ judgements and popularity affect consumers’ assessments of aesthetic quality and music demand. Originality: This will be the first study that investigates empirically the interactive effects of social influence and aesthetic quality in cultural markets.

Practical and Social implications: Arts policy makers as well as marketers of music will benefit from the additional insight generated.
