While the innovation of online digital music stores represents a revolution in the entertainment industry, there is little rigorous academic research that examines the IT aspects of the movement. In this study, we investigate the salient factors that will affect consumers’ acceptance of online digital music stores. Based on the Personal Trait theory, Technology Acceptance Model, and Psychology Flow theory, we propose an integrated conceptual model to explain the emerging phenomena. A simulated lab experiment design and PLS as data analysis method are discussed. The main contribution of this work is theoretical that we identify the factors that may inhibit and promote consumer acceptance of online digital music stores. We demonstrate a way to integrate multiple theories to address the issue. This research extends our understanding of the adoption of online digital music stores. Moreover, the test of the model may assist online digital music stores in improving consumer acceptance.
