Query: Leveraging the structure of musical preference in content-aware music
  recommendation   State-of-the-art music recommendation systems are based on collaborative
filtering, which predicts a user's interest from his listening habits and
similarities with other users' profiles. These approaches are agnostic to the
song content, and therefore face the cold-start problem: they cannot recommend
novel songs without listening history. To tackle this issue, content-aware
recommendation incorporates information about the songs that can be used for
recommending new items. Most methods falling in this category exploit either
user-annotated tags, acoustic features or deeply-learned features.
Consequently, these content features do not have a clear musical meaning, thus
they are not necessarily relevant from a musical preference perspective. In
this work, we propose instead to leverage a model of musical preference which
originates from the field of music psychology. From low-level acoustic features
we extract three factors (arousal, valence and depth), which have been shown
appropriate for describing musical taste. Then we integrate those into a
collaborative filtering framework for content-aware music recommendation.
Experiments conducted on large-scale data show that this approach is able to
address the cold-start problem, while using a compact and meaningful set of
musical features.
