Researchers in the United States have developed a machine learning technique that can accurately predict hit songs with a 97% accuracy rate. Companies struggle to identify songs that will resonate with a large audience as thousands are released every day. Currently, streaming services and radio stations have used human listeners and artificial intelligence approaches to identify hits, however, this has an accuracy rate of only about 50%. The new technique called neuroforecasting, captures neural activity from a small group of people to predict population-level effects without having to measure the brain activity of hundreds of people.
In the study, participants were equipped with off-the-shelf sensors and listened to 24 songs. Scientists measured the participants’ neurophysiologic responses to the songs. This allowed the researchers to predict market outcomes, including the number of streams of a song. The researchers identified hit songs at a success rate of 69% using a linear statistical model. However, when they applied machine learning to the data they collected, the rate of correctly identified hit songs jumped to 97%. This proves that the technique is effective in identifying new songs that are likely to become hits on people’s playlists.
The researchers expect that this approach can likely be used beyond hit song identification. The methodology could be used to predict hits for many other kinds of entertainment, including movies and TV shows, due to its easy implementation. Furthermore, wearable neuroscience technologies could be used in the future to send the right entertainment to audiences based on their neurophysiology.
Despite the near-perfect prediction results, the researchers pointed to some limitations such as the use of a relatively small number of songs in their analysis, and the demographics of the study participants being moderately diverse, but not including members of certain ethnic and age groups.
