In looking at the Billboard top 100 chart for this week there are apparently 4 older Christmas songs in the top 10, and still more in other parts of the chart: https://www.billboard.com/charts/hot-100 This is the first year that I can recall this happening, or at least it being a major news item with Mariah's song being number 1. Has is always been this way, or is it possible that this is happening more because of streaming playing more of a factor in recent years?
