'Holiday' in this context means Christmas

I experimented by replacing, in a Discogs supplied link, 'decade='
with 'year=', and it worked

for example, for the year 1950, Discogs can detail these 582 'Holiday' releases: https://www.discogs.com/search/?style_exact=Holiday&sort=year%2Casc&year=1950

and for 1961, Discogs can detail these 780 'Holiday' releases, which
include albums: https://www.discogs.com/search/?style_exact=Holiday&sort=year%2Casc&year=1961
