System and method for associating music with brain-state data

An intelligent music system comprising:

• at least one bio-signal sensor to capture bio-signal data about a user;
• an output to output music data, the music data comprising at least a first music data item and a second music data item;
• and
• at least one computing device in communication with the least one bio-signal sensor to continuously receive bio-signal data comprising brainwave data of at least one user, the at least one computing device configured to:
• detect a first user response associated with the first music data item, the first user response based on bio-signal data captured during playback of the first music data item;
• detect a second user response associated with the second music data item, the second user response based on bio-signal data captured during playback of the second music data item;
• apply a song transition or a music effect to the music data based on a recommendation generated based on the first user response, the second user response, and a target state using a predictive model.
