a music recommender you can navigate

What is Toposonico?
Toposonico is a music recommender and navigable map for music tracks, artists, albums, and labels. It helps you explore music as a connected landscape rather than as a plain list of search results.
At its core, the system uses a skip-gram word2vec model trained on about 6 million playlists. Music tracks are embedded in a 128-dimensional space, while albums, artists, and labels are derived by aggregating track-level data.
The website presents that model as a 2D map built with UMAP, which makes nearby music entities easier to browse visually. That means the product is designed for discovery, similarity search, and exploratory navigation across a large music graph.
It is best suited for people who want to find related artists or songs, understand musical neighborhoods, or browse a broad catalog through an interactive map. It is also relevant to music researchers, recommender-system enthusiasts, and data-savvy listeners who enjoy exploring embeddings and playlist-based similarity.

Frequently asked questions about Toposonico
What is Toposonico?
Toposonico is a music recommender and navigable map that lets you explore music tracks, artists, albums, and labels through a similarity-based visual interface. It is built to make music discovery feel like moving around a map of related entities rather than browsing isolated search results.
How does Toposonico generate recommendations?
The site says it uses a skip-gram word2vec model trained on about 6 million playlists. Tracks are embedded in a 128-dimensional space, and the higher-level music entities are derived from those track embeddings, which lets the system suggest related items through learned co-occurrence patterns.
What kinds of music entities can I explore?
Toposonico covers four entity types: tracks, artists, albums, and labels. The site presents them as part of one connected music space, so you can move between specific songs and broader musical categories.
What is the map view used for?
The map view is used to browse music visually and see nearby related items in 2D. The site says the 2D map was built with UMAP, which is meant to preserve meaningful neighborhood structure from the underlying embedding space.
How many playlists was the model trained on?
The site states that the core model was trained on approximately 6 million playlists. That training set is the basis for the learned relationships among music items.
What is the embedding size for tracks?
Tracks are embedded in a 128-dimensional space. The site also notes that albums, artists, and labels are computed by aggregating over track-level representations.
Who is Toposonico for?
It is aimed at people who want music discovery tools, especially those who like exploring related artists and songs visually. It also fits researchers, hobbyists, and recommendation-system users who are interested in playlist-based embeddings and navigable music maps.
Does Toposonico show paid plans?
No. The website content available does not list a free tier, subscriptions, one-time purchases, or any other pricing plans.
Can I use Toposonico to discover labels as well as music?
Yes. The site explicitly includes labels alongside tracks, artists, and albums, so label exploration is part of the experience.
Is Toposonico more of a search tool or a discovery tool?
It is more of a discovery tool. The emphasis on embeddings, playlist training, and a navigable map suggests that its main purpose is to reveal relationships and surface adjacent music rather than provide a conventional catalog search interface.
