iTunes release dates

[emotionboy]

Hi,

Looking for clarification on release dates: iTunes lists release dates as original release date (eg 1937 for Disney’s Snow White rather than 2016 for the Signature Collection version). I was under the impression that on Blu-ray.com in the case of Snow White I would use the 2016 date, however if I use this method the amount of iTunes releases with unknown iTunes specific release dates is huge. Please can I have clarification on which release date I should be using (1937 or 2016? If I know the original release date but not the iTunes specific release date should I put the original date or leave it blank?).

Thanks.
