FMA: A Dataset For Music Analysis

International Society for Music Information Retrieval Conference (ISMIR), 2017.

We introduce the Free Music Archive (FMA), an open and easily accessible dataset suitable for evaluating several tasks in MIR, a field concerned with browsing, searching, and organizing large music collections. The community's growing interest in feature and end-to-end learning is however restrained by the limited availability of large audio datasets. The FMA aims to overcome this hurdle by providing 917 GiB and 343 days of Creative Commons-licensed audio from 106,574 tracks from 16,341 artists and 14,854 albums, arranged in a hierarchical taxonomy of 161 genres. It provides full-length and high-quality audio, pre-computed features, together with track- and user-level metadata, tags, and free-form text such as biographies. We here describe the dataset and how it was created, propose a train/validation/test split and three subsets, discuss some suitable MIR tasks, and evaluate some baselines for genre recognition. Code, data, and usage examples are available at https://github.com/mdeff/fma.

• Slides: doi:10.5281/zenodo.1066119
• Poster: doi:10.5281/zenodo.1035847

Data

All metadata and features for all tracks are distributed in fma_metadata.zip (342 MiB). The below tables can be used with pandas or any other data analysis tool. See the paper or the usage.ipynb notebook for a description.

• tracks.csv: per track metadata such as ID, title, artist, genres, tags and play counts, for all 106,574 tracks.
• genres.csv: all 163 genres with name and parent (used to infer the genre hierarchy and top-level genres).
• features.csv: common features extracted with librosa.
• echonest.csv: audio features provided by Echonest (now Spotify) for a subset of 13,129 tracks.

Then, you got various sizes of MP3-encoded audio data:

1. fma_small.zip: 8,000 tracks of 30s, 8 balanced genres (GTZAN-like) (7.2 GiB)
2. fma_medium.zip: 25,000 tracks of 30s, 16 unbalanced genres (22 GiB)
3. fma_large.zip: 106,574 tracks of 30s, 161 unbalanced genres (93 GiB)
4. fma_full.zip: 106,574 untrimmed tracks, 161 unbalanced genres (879 GiB)

See the wiki (or #41) for known issues (errata).

Code

The following notebooks, scripts, and modules have been developed for the dataset.

1. usage.ipynb: shows how to load the datasets and develop, train, and test your own models with it.
2. analysis.ipynb: exploration of the metadata, data, and features. Creates the figures used in the paper.
3. baselines.ipynb: baseline models for genre recognition, both from audio and features.
4. features.py: features extraction from the audio (used to create features.csv).
5. webapi.ipynb: query the web API of the FMA. Can be used to update the dataset.
6. creation.ipynb: creation of the dataset (used to create tracks.csv and genres.csv).
7. creation.py: creation of the dataset (long-running data collection and processing).
8. utils.py: helper functions and classes.

Usage

  Click the binder badge to play with the code and data from your browser without installing anything.

1. Clone the repository.

   git clone https://github.com/mdeff/fma.git
   cd fma

2. Create a Python 3.6 environment.

   # with https://conda.io
   conda create -n fma python=3.6
   conda activate fma
   
   # with https://github.com/pyenv/pyenv
   pyenv install 3.6.0
   pyenv virtualenv 3.6.0 fma
   pyenv activate fma
   
   # with https://pipenv.pypa.io
   pipenv --python 3.6
   pipenv shell
   
   # with https://docs.python.org/3/tutorial/venv.html
   python3.6 -m venv ./env
   source ./env/bin/activate

3. Install dependencies.

   pip install --upgrade pip setuptools wheel
   pip install numpy==1.12.1  # workaround resampy's bogus setup.py
   pip install -r requirements.txt

   Note: you may need to install ffmpeg or graphviz depending on your usage.
   Note: install CUDA to train neural networks on GPUs (see Tensorflow's instructions).

4. Download some data, verify its integrity, and uncompress the archives.

   cd data
   
   curl -O https://os.unil.cloud.switch.ch/fma/fma_metadata.zip
   curl -O https://os.unil.cloud.switch.ch/fma/fma_small.zip
   curl -O https://os.unil.cloud.switch.ch/fma/fma_medium.zip
   curl -O https://os.unil.cloud.switch.ch/fma/fma_large.zip
   curl -O https://os.unil.cloud.switch.ch/fma/fma_full.zip
   
   echo "f0df49ffe5f2a6008d7dc83c6915b31835dfe733  fma_metadata.zip" | sha1sum -c -
   echo "ade154f733639d52e35e32f5593efe5be76c6d70  fma_small.zip"    | sha1sum -c -
   echo "c67b69ea232021025fca9231fc1c7c1a063ab50b  fma_medium.zip"   | sha1sum -c -
   echo "497109f4dd721066b5ce5e5f250ec604dc78939e  fma_large.zip"    | sha1sum -c -
   echo "0f0ace23fbe9ba30ecb7e95f763e435ea802b8ab  fma_full.zip"     | sha1sum -c -
   
   unzip fma_metadata.zip
   unzip fma_small.zip
   unzip fma_medium.zip
   unzip fma_large.zip
   unzip fma_full.zip
   
   cd ..

   Note: try 7zip if decompression errors. It might be an unsupported compression issue.

5. Fill a .env configuration file (at repository's root) with the following content.

   AUDIO_DIR=./data/fma_small/  # the path to a decompressed fma_*.zip
   FMA_KEY=MYKEY  # only if you want to query the freemusicarchive.org API
   

6. Open Jupyter or run a notebook.

   jupyter notebook
   make usage.ipynb
