What is Unheard.FM?
Music discovery for Spotify that you control—Unbiased, unsponsored, and always fresh.
Unheard.FM generates an on-demand, curated mix that is instantly ready in your Spotify library based on your rules, not your past listening history. It uses library-wide filtering and random selection to guarantee you bypass the typical algorithmic bubble and find truly new music with no repeats, ever.
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 control and truly fresh results with these key features:

Features
No Repeats. Ever.
Your discovery is always fresh. Our app automatically filters out songs from your liked tracks, playlists, top tracks, and recently played to only serve you tracks you haven't heard before, based on your library.
Full Control. Precision Filters.
Your discovery is 100% up to you. Customize your discovery by genre, decade, individual years, popularity, and more. You have precision control to easily exclude artists, genres, or replace tracks right in the playlist.
Interactive Listening
Your discovery model can evolve in real-time by giving feedback on a track's genre, decade, or artist. In a different mood? Add or subtract styles and artists anytime, immediately. No need to "retrain" your suggestions since they are no longer solely based on your listening history!
Unbiased Discovery
Our algorithm digs deeper into genres and overlooked tracks by using a randomized approach while applying your preferences and normalizing popularity based on the song's release year. This gives you an unbiased, truly fresh feed.
On-Demand Mixes
Build an evolving discovery model to generate playlists continually or create a specific mix in seconds. No waiting a day (or a week) for "made for you" playlists and mixes—get your music now.
Real-Time Results
Everything is pulled directly from Spotify when mixes are generated. Spotify's catalog is expanding and evolving constantly. With direct sourcing there are no outdated models, no stale suggestions, just fresh music.
How It Works
Step 1: Configure
Choose genres, years, and popularity settings to shape your discovery model.

Step 2: Generate and Tweak
Create a fresh playlist based on your preferences. Swap out tracks or filter what you don't like.

Step 3: Listen on Spotify
Instantly open your playlist in Spotify and hear what you've been missing.

Step 4: Explore in Now Playing
Use Now Playing mode to interact with each track in real time. Mark what you like or don't like based on genre, decade, or artist — and your model will evolve as you go.

Step 5: Refine and Restart the Discovery
Refine your preferences whenever you like to keep the discovery fresh and aligned with your taste. Your feedback in Steps 2 and 4 helps you create a better mix every time you generate a new one.
