Dataset Overview

Each row represents ONE track (Spotify track_id), enriched with:

• Track metadata (name / ISRC / popularity / explicit)
• Primary artist (id / name / popularity / genres)
• Album metadata (id / name / release year)
• Spotify audio features (danceability, energy, etc.)

Dataset size: 45,059,660 rows

Sorted by: popularity (desc), track_id (asc)

Filtering Rules

• Track selection: tracks with popularity >= 1 (Spotify 0..100 scale)
• Audio features selection: keep only records with null_response == 0

Indexes

We create two categorical indices for compact downstream modeling:

artist_idx

• Range: 0..N
• 0 is reserved for missing/empty/"<UNK>" artist_name
• 1..N are assigned by descending artist popularity (higher popularity => smaller index)

artist_genre_idx

• Range: 0..M
• 0 is reserved for missing/empty/"<UNK>"
• We obtained data from everynoise.com, and use specialized formulas to calculate the optimal genre for each artist (Docs -> v0.4 chapter)
• If an artist has a valid artist_genre_idx but the artist_genres is empty, it means artist_genre_idx is inferred based on related artists
• 1..M are assigned by everynoise.com (https://everynoise.com/everynoise1d.html)
