Claim:
1. A method for deriving optimal discriminating features indicative of a subject state when the subject listens to one of a set of musical pieces, the method comprising: extracting frequency features from the subject's EEG signal when the subject is in a first subject state and a second subject state, the frequency features being extracted from more than one frequency band in one set of time segments; identifying optimal discriminating features from the extracted frequency features, the optimal discriminating features indicative of characteristics of the EEG signal when the subject is in the first subject state and the second subject state; extracting musical features associated with each of the set of the musical pieces; and comparing the extracted musical features with the optimal discriminating features to determine which of the extracted musical features are indicative of characteristics of musical pieces that the subject prefers, wherein one of the first subject state and the second subject state indicates that the subject prefers a musical piece while the other state indicates that the subject does not prefer the musical piece.
