I try to get as close as possible to the downloaded album.
In your example for The Smiths and "The Queen is Dead" I search only for the matching album or use one of the existing web sources scripts:
Then I check and compare:
Is it a CD? Or "12" Vinyl LP"?
Does it have 10 or 23 or more tracks?
Does it have a unique barcode or catalog# or any other uniquely identifying info?
If the online sources like MusicBrainz or Discogs does not have a specific album, I search the closest one (Year, number of Tracks, Country, Media...)
Most online sources also have additional informations like "green vinyl" which can be tagged as SUBTITLE or something like this. All other informations (Barcode, Catalog number, Label etc.) I can get from the source. In the best case a web source script tags my album nearly automatically for me.
