  We examine user and song identification from neural (EEG) signals. Owing to
perceptual subjectivity in human-media interaction, music identification from
brain signals is a challenging task. We demonstrate that subjective differences
in music perception aid user identification, but hinder song identification. In
an attempt to address intrinsic complexities in music identification, we
provide empirical evidence on the role of enjoyment in song recognition. Our
findings reveal that considering song enjoyment as an additional factor can
improve EEG-based song recognition.
