Song Recommender with Unsupervised Machine Learning and Python: A Step-By-Step Coding Tutorial

This tutorial explains how Spotify uses machine learning to recommend songs. It covers the implementation of the K-means algorithm using Python in Google Colab, including data preprocessing, clustering, and evaluating song recommendations. The tutorial also provides functions for comparing the accuracy of recommendations against random selections.
