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 (ChristianDance.eu) 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.

"King, Lamb, Lion" by Ben Jero & Graham Guy: When the World Runs Dry

What happens when the world just isn’t enough?  In early 2025, Graham Guy was reading Revelation chapter 4. The picture of heaven gathered around the throne — declaring God holy and worthy of praise — planted the seed for this song. Three words surfaced from that moment: “King, Lamb, Lion.” Graham sent them to Ben Jero, and across a string of FaceTime calls between South Carolina and California, the song “King, Lamb, Lion” took shape.  The opening verse doesn’t pretend. “I’ve tried this world, but it won’t fill me,” the lyric admits, before landing at surrender: “My life laid down, at your feet.” That’s honest territory. Most of us have chased something we thought would satisfy, only to find ourselves empty-handed. The song changes our focus to lasting results. “The old is gone, the new has come,” it declares, repeating a promise found in 2 Corinthians 5:17: “If anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.” Notice what that ...

"Stand By Me" by Daniel Aranda: Finding Steadiness in Life's Storms

Who’s standing with you in the storm? “Stand By Me” by Daniel Aranda is an amazing rendition of a hymn written by Charles Albert Tindley in 1905. Tindley was the son of a former slave, a man who knew what it meant to need help that wasn’t guaranteed. He didn’t write from comfort. He wrote from the middle of a fight, and that’s exactly why the song is still so relevant and cherished by many today. Daniel Aranda’s recording brings gospel legends Terry Blackwood and Charlie McCoy into that same lineage, carrying Tindley’s plea forward into a new generation.  The lyrics move through life’s troubles, one verse at a time. “When the storms of life are raging, stand by me”  — that’s not poetic exaggeration. Tindley’s first verse is about a ship tossed on open water, powerless against the waves. Then verses about failing strength, friends who misunderstand your best efforts, persecution, and the song ends with a verse about old age creeping toward “chilly Jordan.” Each of the verses names ...

"Returning - Live" by Victory House Worship: Waiting with Fire in Our Lamps

“Returning — Live” by Victory House Worship makes us aware that all of creation seems to hold its breath. “The earth is groaning for redemption, Creation reaches for Her King.” That’s the present-day reality that the apostle Paul described centuries ago, and Victory House Worship beautifully captures that in this song. The lyrics don’t dwell only on what Jesus already did at the cross; it looks forward. “The oil in our lamps is burning, For Him who was and is and is returning.” That line carries the whole weight of our Christian hope: Past, present, and future, all coming together in One. Jesus! The bridges elaborates on this hope, comparing His first coming with His second coming. “Though You came as a Lamb, You’ll return as a Lion.” Gentleness gave way to sacrifice once. With His next coming, sacrifice will give way to triumph. Romans 8:22–23 describes the groaning: “the whole creation has been groaning together in the pains of childbirth until now… waiting eagerly for adoption as...
