  Music therapy has emerged recently as a successful intervention that improves
patient's outcome in a large range of neurological and mood disorders without
adverse effects. Brain networks are entrained to music in ways that can be
explained both via top-down and bottom-up processes. In particular, the direct
interaction of auditory with the motor and the reward system via a predictive
framework explains the efficacy of music-based interventions in motor
rehabilitation. In this manuscript, we provide a brief overview of current
theories of music perception and processing. Subsequently, we summarise
evidence of music-based interventions primarily in motor, emotional and
cardiovascular regulation. We highlight opportunities to improve quality of
life and reduce stress beyond the clinic environment and in healthy
individuals. This relatively unexplored area requires an understanding of how
we can personalise and automate music selection processes to fit individuals
needs and tasks via feedback loops mediated by measurements of
neuro-physiological responses.
