Behind the Scenes: Spotify's Music Categorization Algorithms

Have you ever wondered how Spotify categorizes songs and recommends them to users? 

This is how our listings help you as an artist! 

While Spotify does not publicly disclose the details of its algorithms, ChristianDance has incorporated a number of key factors in the content that is published. What follows are some of the key factors that industry experts believe are most likely to impact how Spotify categorizes music. 

Spotify uses a combination of automated algorithms and human curation to determine the genre and category of music. 
  • Audio Analysis: Spotify uses audio analysis techniques to understand the characteristics of a song. This includes examining tempo, rhythm, instrumentation, and tonal qualities. These characteristics can help determine a song's genre or style.

  • User-Generated Data: Spotify collects a massive amount of user-generated data, such as listening habits, playlists, and user-created tags. They use this information to learn how users categorize and associate songs with genres and moods. If a large number of users consistently label a song (or an artist) as "rock" or "pop," this can have an impact on its classification.

    This is where the importance of playlists and their listeners comes in. The overall content of the playlist will influence the classification of other songs on that same playlist. That is why it is essential to understand where your music is being added. 

  • Collaborative Filtering: Spotify uses collaborative filtering techniques to recommend music to users based on their listening history and preferences. If users who enjoy a certain set of songs also enjoy others with similar characteristics, this will help in categorizing songs into genres or categories.

    For example, website or Facebook visitors who click on songs (e.g. on Spotify). If they listen to more Christian music on Spotify, the classification of a song will be affected. That is one of the reasons why ChristianDance includes a Spotify web player in the posts, so visitors can listen to the song... and at the same time help Spotify classify it. The embedded Spotify web player can detect if the page is loaded by someone who is logged into a Spotify account. The fact that a Spotify user is interested in a web page that contains an embedded Spotify song/album is enough to help  Spotify classify it... even if the visitor doesn't click 'play'. 

  • Content Analysis: Textual data associated with songs and albums, such as artist biographies, song titles, and album descriptions, may also be considered by Spotify. Keywords and phrases can reveal information about a song's genre or style.

    This is where the categories that artists themselves select when they upload their music start to push the final classification of their music in a specific direction. 

  • Expert Curators: Spotify uses music experts and curators to assist with song classification and playlist creation. To improve the accuracy of recommendations and categorization, these experts may manually tag songs with genres, moods, and styles.

    We're not sure if Spotify considers us ( an expert curator (yet). Spotify does not always notify you when that is the case...  We frequently do see artist profiles with one of our playlists listed in the 'Discovered on...' section. 

  • Machine Learning and AI: Spotify processes and analyzes the data mentioned above using machine learning and artificial intelligence algorithms. These algorithms constantly improve their recommendations and categorization based on user interactions.
It's important to note that genre and category labels can vary in accuracy, and there may be overlap between genres. Music is highly subjective, and one person's definition of "pop" may differ from another's. Spotify's goal is to provide personalized recommendations and categorizations based on the preferences and listening habits of each user.
