SongSimilar

Similarity comes from music listening data: when many of the people who play one song also play another, the two are rated as similar. We use the Last.fm and Deezer APIs for this, and MusicBrainz for release years. When a song has few direct matches, we fall back to similar artists and their most popular tracks.

For well-known songs they are very reliable, because the match score reflects real co-listening across a huge audience. Obscure or very new tracks have less data, so their results lean on similar artists instead. Those results are marked with an asterisk and scored 15% lower, so direct matches always rank first.

It is a relative similarity score from 0 to 100%. The top result is the song's closest neighbour, and scores further down mean a weaker connection. Compare scores within one list rather than across different songs, since popular songs simply have more listening data behind them.

Spotify Radio needs the app and an account, mixes in songs you already know, and only plays what is on Spotify. SongSimilar works in any browser with no signup, shows the whole ranked list up front with match scores, and lets you open each song on YouTube, Spotify or Amazon Music.

Yes. The similar song finder is completely free and you don't need an account to use it. The site is supported by ads and affiliate links. Favorites and recent searches are stored in your own browser; if you choose to sign in, your favorites are also saved to your account so they sync across devices.

Check the spelling and add the artist name, because many songs share a title. Very new releases, remixes and small local artists may not have enough listening data yet. If you see a message about too many searches, wait a minute and try again.
