Current Challenges and Visions in Music Recommender Systems Research
Music recommender systems (MRS) have experienced a boom in recent years,
thanks to the emergence and success of online streaming services, which
nowadays make available almost all music in the world at the user's fingertip.
While today's MRS considerably help users to find interesting music in these
huge catalogs, MRS research is still facing substantial challenges. In
particular when it comes to build, incorporate, and evaluate recommendation
strategies that integrate information beyond simple user--item interactions or
content-based descriptors, but dig deep into the very essence of listener
needs, preferences, and intentions, MRS research becomes a big endeavor and
related publications quite sparse.
The purpose of this trends and survey article is twofold. We first identify
and shed light on what we believe are the most pressing challenges MRS research
is facing, from both academic and industry perspectives. We review the state of
the art towards solving these challenges and discuss its limitations. Second,
we detail possible future directions and visions we contemplate for the further
evolution of the field. The article should therefore serve two purposes: giving
the interested reader an overview of current challenges in MRS research and
providing guidance for young researchers by identifying interesting, yet
under-researched, directions in the field
DJ-MC: A Reinforcement-Learning Agent for Music Playlist Recommendation
In recent years, there has been growing focus on the study of automated
recommender systems. Music recommendation systems serve as a prominent domain
for such works, both from an academic and a commercial perspective. A
fundamental aspect of music perception is that music is experienced in temporal
context and in sequence. In this work we present DJ-MC, a novel
reinforcement-learning framework for music recommendation that does not
recommend songs individually but rather song sequences, or playlists, based on
a model of preferences for both songs and song transitions. The model is
learned online and is uniquely adapted for each listener. To reduce exploration
time, DJ-MC exploits user feedback to initialize a model, which it subsequently
updates by reinforcement. We evaluate our framework with human participants
using both real song and playlist data. Our results indicate that DJ-MC's
ability to recommend sequences of songs provides a significant improvement over
more straightforward approaches, which do not take transitions into account.Comment: -Updated to the most recent and completed version (to be presented at

Exploring Musical, Lyrical, and Network Dimensions of Music Sharing Among Depression Individuals
Depression has emerged as a significant mental health concern due to a
variety of factors, reflecting broader societal and individual challenges.
Within the digital era, social media has become an important platform for
individuals navigating through depression, enabling them to express their
emotional and mental states through various mediums, notably music.
Specifically, their music preferences, manifested through sharing practices,
inadvertently offer a glimpse into their psychological and emotional
landscapes. This work seeks to study the differences in music preferences
between individuals diagnosed with depression and non-diagnosed individuals,
exploring numerous facets of music, including musical features, lyrics, and
musical networks. The music preferences of individuals with depression through
music sharing on social media, reveal notable differences in musical features
and topics and language use of lyrics compared to non-depressed individuals. We
find the network information enhances understanding of the link between music
listening patterns. The result highlights a potential echo-chamber effect,
where depression individual's musical choices may inadvertently perpetuate
depressive moods and emotions. In sum, this study underscores the significance
of examining music's various aspects to grasp its relationship with mental
health, offering insights for personalized music interventions and
recommendation algorithms that could benefit individuals with depression.Comment: arXiv admin note: text overlap with arXiv:2007.03137,

Procyon LLC: From Music Recommendations to Preference Mapping
Procyon LLC had re-launched and renamed their music discovery site, Electra, to Capella, in 2008. Its core strength had originated from Electra’s proprietary technology, which used music libraries from real people, its members, to generating “automated word-of-mouth” recommendations, targeted advertising and editorial content. With the re-launch, Capella’s focus changed from a business-to-consumer destination site to a demonstration site for Procyon as it pursued a new business-to-business strategy. What led Procyon to make this strategic change? What products and services should it market, and to whom? This case describes the transition from music recommendation to preference mapping, and provides students with a variety of alternative partnering options to consider as they move forward
The Impact of Spotify’s AI-Driven Music Recommender on User Listener Habits
This study explores how Spotify uses AI-technology to collect data about the user’s music listening behavior and serve personalized music recommendations based on their music taste and listening habits. It also involves a quantitative survey to discover the impact these AI- driven algorithms have on the Spotify users, especially focusing on four carefully chosen aspects: the user’s satisfaction with the music recommendations, the correlation between their satisfaction and their user activity, their selectivity in song choices and their ways of discovering new music. The results from the survey indicates that there is an overall satisfaction with the music personalization, especially for the most active users. Also, their reports indicate that they prefer the mix between familiarity and music discovery, and that they don’t believe the recommendations have a significant impact on their selectivity
