Yep that’s the entry for the original 12" Vinyl LP release, which did indeed come out in 1980.
Many things can dictate needing a new release entity, different formats is one of the most common.
You should always try and have the Release Date be as close to the actual release date of the medium you’re entering, sometimes this isn’t very easy to establish and so some editors may revert to using things like the latest Copyright date or Phonographic date printed on the release - which is OK but not a sure fire way of confirming the release. Ultimately if you were really unsure on the date you are more than welcome to leave that field blank, it is not a required field to create the entry.
As you progress you’ll get a sixth-sense almost when working out if a date printed either on the release, or referenced elsewhere (such as another database/marketplace) is genuine or not.
To help us control this field’s validity, the form will reference the date in which the format selected was introduced to the date entered on the first page (in this case CD’s after 1982 are generally accepted). A lot of the entries in that naughty report are historic bad data that editors are slowly unravelling.
Shouldn’t be a problem you’ve got the eyes of many autoeditors now on this who are all equipped to help newcomers like yourself, as maybe if you stick around and continue to do a good job you could gain that status yourself.
If you’re ever unsure my suggestion is to just make a single edit, and then either return here to the forums to ask or make a post in this long-thread:
