The Guardian’s Comment Is Free section seems to have far more commentators/columnists than a print newspaper could support. It seems mostly like a free-for-all which pumps out a huge amount of content - only a small amount of which is good.
I assume that’s due to digital media capabilities/considerations and that the paper is a little more selective.
As for Ed Sheeran specifically, I can’t see much reason to dislike him - other than an inevitable backlash against anything popular.
I can’t say I’m a huge fan, but his songs strike me as fine… some are catchy, some have decent lyrics, they tend to address issues that throw away pop often doesn’t. He isn’t manufactured and he’s managed to become popular based on his music (whatever you think of it) rather than being handsome or fashionable or a good dancer or whatever 90% of 80s pop stars became popular based on.
If I was forced to spend a year on a desert island with only the music of one big recent pop star to listen to, I think there would be a lot of worse options.
(If anyone can explain the popularity of Drake to me then I’d deeply appreciate it - Other than the fact he was in Degrassi Jr High.).
