Question 1

What is Resonance?

Accepted Answer

Resonance is a free music discovery site that surfaces underground artists with unusually devoted fanbases. We measure engagement depth — plays per listener, track depth, and cross-platform ratios — to find artists whose tiny audiences can't stop listening.

Question 2

How does Resonance find underground artists?

Accepted Answer

We combine data from Deezer, Last.fm, and social platforms. Nine noise filters remove false positives (major labels, already-famous artists, social media stars with 50K+ followers). Three engagement signals — plays per listener, track depth, and listener/fan ratio — are scored independently of popularity (r=0.013 correlation with listener count).

Question 3

What does 'plays per listener' mean?

Accepted Answer

Plays per listener (PPL) measures how many times the average listener plays an artist's music. A high PPL means fans keep coming back — it's a signal of genuine devotion rather than one-time curiosity. The median across all artists is about 15 plays per listener.

Question 4

What does 'sounds like' mean on artist pages?

Accepted Answer

Each artist's top tracks are analyzed using MERT, a neural audio model that creates 768-dimensional embeddings of the actual sound. These are compared against 1,100+ well-known reference artists to find the closest sonic matches. It's based on what the music sounds like, not tags or genres.

Question 5

Is Resonance free?

Accepted Answer

Yes, Resonance is completely free. Browse artists by genre, explore engagement data, and discover music you can't find anywhere else — no account required.
