"This", as they say, and what others have said. I think we forget sometimes that the vast majority of people don't actually give much of a shit about music. It's just something on the radio or that you see on telly sometimes. I think us music fans sort of find ourselves in a bubble sometimes, because music is so much a part of our lives, we forget that not everyone is the same. In that population of 64 million, don't forget that includes babies, children, pensioners and nearly-dead people, none of whom would be bothered about Adele. Her album was an "event" one - people who don't normally buy albums bought it because so many other people did. The same is happening with Ed Sheeran's album.
