Known issues (errata)

Below are issues affecting the rc1 data release that cannot be fixed without a data update. As updating is disruptive (it'll break code and make results non-comparable), it should be done sparingly, e.g., to fix a fatal flaw or many small ones discovered over time. See also #41.

Excerpts shorter than 30s and erroneous audio length metadata

Issues: #4, #8, #36, #44, #49.

Due to erroneous length metadata, some tracks (in fma_small.zip, fma_medium.zip, and fma_large.zip) have less than 30s of audio. Libraries might crash when loading files with no audio at all (length 0s). Your best option is to ignore those files or catch library errors.

Erroneous ID3 tags

Issue: #27.

Erroneous ID3 tags in some tracks might induce some software to wrongly believe that those tracks were encoded at an exceedingly large bitrate (>100M). An option is to remove all ID3 tags.
