TrackEnrichmentData

releaseDate is a string and not datetime because it is a partial date: MusicBrainz answers 1997, 1997-06 or 1997-06-24 depending on what is actually known about the release, and the SDK types it the same way. A datetime would reject the first two or invent a day and a time for them, which is a precision the source never claimed.
