Music Discovery for Spotify

What is Unheard.FM?

Music discovery for Spotify that you control—No assumptions, no sponsors, no repeats.

Unheard.FM is a music discovery web app for Spotify that generates fresh playlists based on your rules, not your listening history. It delivers unbiased, non-sponsored content by focusing on what you want to hear—not what an algorithm thinks you want.

This app is for people who:

Want to find new music without being spoon-fed assumptions.
Need powerful filters to track down specific music by decade, genre, or obscurity.
Are tired of hearing the same songs and want something truly new.

The Problem with Music Discovery

Tired of hearing the same songs on repeat? Modern music discovery is broken. It's opaque, and it keeps you stuck in a comfort zone of safe, sponsored recommendations.

"How do you know what you like if you've never listened to it before?"

The Unheard.FM Solution

Unheard.FM puts the "discovery" back in music, giving you complete control and truly fresh results with these key features:

Find New Music: Our engine finds fresh tracks based only on the rules you set.
No Repeats, Ever: We automatically exclude songs from your liked tracks, playlists, top tracks, and recently played.
Total Control: You can filter by artists, genres, year, and decade to discover exactly what you're looking for.
