FMAK: A Dataset of Key and Mode Annotations for the Free Music Archive

We present a new expert-labeled dataset for the evaluation of key detection containing 340 hours (5489 songs) of song-level key and mode annotations, spread across 17 genres. 

For each song, we provide annotations for:

• FMA track id
• Spotify URI (when available)
• Key and mode

All the audio is collected in and distributed by the FMA dataset by Michael Defferrard, Kirell Benzi, Pierre Vandergheynst, and Xavier Bresson.

• The FMA metadata is made freely available for public use under a Creative Commons license
• We do not hold the copyright on the audio and distribute it under the license chosen by the artist
• The dataset is meant for research purposes
