The half-right argument is that music can enhance learning. Experiments have shown that happy instrumental music improves mood and performance on mundane or straightforward tasks. However, background music interferes when tasks require sustained concentration, especially if it includes lyrics. Also, individual differences such as working memory capacity play an important role in whether music supports or hinders learning.

Evidence clearly shows that listening to quick instrumental music boosts mood and elevates cognitive function on simple or monotonous tasks. On the contrary, when faced with complicated work requiring intense focus, background music, especially with words, proves to be distracting. Besides, individual variation, i.e., working memory capacity, plays a major role in determining whether music supports or interferes with learning.

Scientific research indicates that listening to upbeat instrumental music can improve mood and cognitive performance on simple or repetitive tasks. However, for more complex tasks requiring high levels of concentration, background music—particularly if it contains lyrics, can be distracting. Furthermore, individual differences such as working memory capacity have a significant influence on whether music aids or impedes learning.
