Song playlist recommendation system
I want to build a recommender system to suggest similar songs to continue a playlist (similar to what Spotify does by recommending similar songs at the end of a playlist).
I want to build two models: one based on collaborative filtering and another one, a content-based model, to compare their results and choose the best one.
Now, I have two questions:
- Where can I find a dataset with useful data for this type of work?
- How can I measure the results to choose the best model? How can I understand that a specific song is better than another one to continue my playlist?
