What's in the dataset

The Resonance dataset is built by combining three layers of data for every track that appeared in the Billboard Hot 100 Year-End charts from 1960 to 2025.

Chart metadata

Track title, artist, year, chart position. Scraped from Billboard's official year-end Hot 100 archives.

6,598 / 6,598 (100%)
📊

Audio features

Valence, energy, danceability, loudness, tempo, mode, speechiness, acousticness, instrumentalness, liveness, duration. Extracted via Spotify and Deezer APIs.

🧠

Brain activation maps

Predicted cortical activation from TRIBE v2, an fMRI-trained neural network. 20,484 vertices grouped into 6 functional brain regions: Auditory, Motor, Language, Emotion, Prefrontal, Visual.

6,458 / 6,598 (98%)

Lyrics

Lyrics were retrieved via the LRClib API, matching by track title and artist. Since audio previews are limited to 30-second clips, the average word count per track is approximately 50 words, representing a snapshot rather than full lyrics.

How it was built

1

Chart scraping

Billboard Hot 100 Year-End charts from 1960 to 2025, parsed into structured records (title, artist, rank, year).

2

Audio matching

Each track was matched to a Spotify ID via the Search API. For unmatched tracks, Deezer was used as fallback. Audio features were extracted via the respective APIs.

3

Brain prediction

30-second audio previews were processed through TRIBE v2, generating predicted cortical activation maps (20,484 vertices × 30 timesteps). Vertices were grouped into 6 functional regions based on a neuroanatomical atlas.

4

Lyrics retrieval

Lyrics matched via LRClib API by title and artist. 5,490 out of 6,598 tracks matched (83%). Average ~50 words per track from 30-second previews.

5

Storage

All data stored in PostgreSQL, with pre-computed JSON exports for each exploration. No external dependencies at runtime.
