For historical reasons there is some confusion between Tracks[1] and Recordings[2] in MusicBrainz. Essentially what should be saved to `MUSICBRAINZ_TRACKID` is the Recording MBID—which is what whipper is correctly doing, but the value storing this value was called `mbidTrack` rather than `mbidRecording`, which could potentially cause confusion.
