MusicBrainz, and beets, has separate date fields for both those things. "original_year" is the year of the original release, and "year" is the year of the release of your version of the album. I have my beets configured to include original_year at the beginning of the album folder name, and then the release year in parenthesis at the end, but only if it is different.
