With over 82 million songs, 4 billion playlists, and 456M users, Spotify is a name to reckon with in the streaming industry. Spotify is an audio-streaming application owned by Daniel Ek and Martin Lorentzon. Spotify uses machine learning models to enhance the recommendation-making process for all its users.
How Spotify uses Machine Learning?
In its initial years, Spotify used machine learning algorithms like collaborative filtering to recommend music to its subscribers. It uses NLP as well to improvise recommendations along with reinforcement learning.

Collaborative Filtering
It is a recommendation model that tries to estimate user preferences based on data collected from different users. The parameters, user playlists, user listening behaviors, information about specific tracks or podcasts, and analytics that illustrate how users browse, what they click on, and even what they skip or like, are fed to the model to help it understand user preferences. Apart from this, the app also uses simulators to evaluate recommendations for training the machine learning algorithm. Furthermore, the app also uses machine learning algorithms for blending playlists among different users.
Natural Language Processing
Spotify uses NLP for songs-categorization. It uses content available on different websites in the form of blogs, articles, etc., with the help of web scraping methods to understand how the audience perceives new music. Songs' lyrics are fed to an NLP model, and keywords are assigned weights to analyze the song's emotion. Additionally, Spotify uses NLP for tracking metadata.

Spotify Reinforcement Learning
Spotify uses reinforcement learning to recommend just the right songs to its user. The user behavior while playing a particular song is analyzed to make predictions and deduce sustainable, diverse, and fulfilling recommendations for the users. Many users enjoy listening to new songs served to them through Double Weekly playlists.
On the other hand, Spotify's Vice President of Personalization Oskar Stål mentioned, "rather than handing users the empty calories of a content diet that will only satisfy them in the movement, RL aims to push them to a more sustainable, diverse, and fulfilling content diet."
Apart from machine learning, Spotify has editors at the backend who create customized user recommendations. Additionally, Spotify has focussed on giving its users a fantastic user interface that makes it an attractive choice for users worldwide. Their UI is one of the prime reasons why users use the app repeatedly. As per the company's head of machine learning, Tony Jabara, their team believes that personalized recommendations should be created to deliver a lifetime of content instead of optimizing for the next click.
