Do young people even watch TV, really? Most of the "young" brands and ads targeted at the youth are using contemporary music, from what I've heard, but I don't really watch TV and am a prodigious ad blocker when online. You've mentioned Tesco before, who don't seem to be playing the old hits? The way young people are exposed to music has changed quite dramatically this century, from early file sharing through streaming and now just background noise on a tiktok video or computer game. It's a generalisation, yes, but, it seems like the most recent generations don't define their lives through music like many of us older heads on here used to. They don't purchase it, that's a completely alien concept, and they don't consume it in the same way a lot of us do, so our old way of measuring popularity does not really convey what's going on.
