Interesting, I did some research and found:
'Results from the current study demonstrated how important it is to consider the effects of distracting music on cognitive performance. It was shown that the volume plays a crucial role and could be more important than the type of music played. However, data from this study has demonstrated that silence seems to be the best environment to maximize performance when engaging in cognitive activity. Classical music was not shown to enhance performance contrary to the study’s expectations. Hence, the direct benefits of listening to music on cognitive processing could be more of a fantasy than a reality'
