I don't see any of these changes documented in the object model:

• https://developer.spotify.com/documentation/web-api/reference/object-model/#track-object-simplified
• https://developer.spotify.com/documentation/web-api/reference/object-model/#album-object-simplified

Might be worth filing an issue upstream at https://github.com/spotify/web-api/issues. I'm hesitant to include code that depends upon observable but undocumented behavior.

@zmb3 i've corrected the format, also submitted a issue in https://github.com/spotify/web-api/issues/1314 .

Thanks @rociiu - let's see what they say on the upstream issue.
