Song Describer Dataset Data Card

Dataset Overview

Subset Tracks Captions Annotators Cap len (avg) Vocab size Audio len
full 706 1106 142 21.7 ± 12.4 2859 ~ 2 min
valid 546 746 114 18.2 ± 7.6 1942 ~ 2 min

Dataset Structure

The dataset is structured as follows:

  • audio: contains the audio files organised in subfolders
    • 00
      • audio_id_xx.2min.mp3
      • ...
    • ...
  • song_describer.csv: main csv file containing the data annotations and metadata
  • audio_licenses.txt: text file with the audio licenses for each track in the dataset
  • song_describer.mtg-jamendo.tsv: MTG-Jamendo metadata for each track in the dataset

Each instance in the metadata contained in song_describer.csv contains the following fields:

"caption_id": 001, # unique id assigned to the caption
"track_id": 0000001, # unique id for the track (from Jamendo)
"caption": "this is a music caption", # text description of the track
"is_valid_subset": True, # whether the caption is part of the validated subset
"familiarity": 1, # 0-5 rating of the annotator's familiarity to the kind music in the track
"artist_id": 000001, # unique id for the track's artist (from MTG-Jamendo)
"album_id": 000001, # unique id for the track's album (from MTG-Jamendo)
"path": 00/<track_id>.mp3, # relative path to the audio file
"duration": 202.5, # duration of the original track in seconds (from MTG-Jamendo)
"genre": ["genre_1", "genre_2"], # list of genre tags (from MTG-Jamendo)
"instrument": [], # (from MTG-Jamendo)
"mood/theme": ["mood/theme_1", "mood/theme_2", "mood/theme_3",], # (from MTG-Jamendo)

We provide a single split for the dataset, as it is solely intended for evaluation.

All the audio files are in 320kbps MP3 format.

Dataset Creation

The Song Describer Dataset was developed as a benchmark dataset for evaluating models on music-and-language (M&L) tasks.

Data Collection

The audio in the Song Describer Dataset comes from the split-0 test split of the MTG-Jamendo dataset. The annotations (captions) were crowdsourced via the Song Describer platform.
