A number of researchers have indeed suggested that musical hallucinations constitute the auditory equivalent of the Charles Bonnet syndrome, since they are so frequently associated with hearing loss. However, they also occur in people who have no hearing loss, so this can only be part of the picture. It may account for a subset of the cases, though.
