They need to create that Christmas catalogue single chart where all songs over a certain age don't chart in the main chart. Just publish it from the last week of November or whenever it is they start to impact and then bin it from January as nobody wants to look at a chart full of Mr Brightside and Ed Sheeran anyway.
The rest of the year (like RUTH now), let them feature in the main chart as there is a proper demand for it rather than being driven by playlists, and it so rarely happens it'll barely register most weeks.
