Yeah because popularity is an indication of quality.
Go one direction!
Not quality no. But I will accept that One Direction have a huge appeal. That appeal is amongst young girls, who haven't the foggiest about music. If they were all ugly, do you think they'd have this success? They wouldn't have a chance. They're very popular, but amongst an unenlightened audience.
Arctic Monkeys are also popular, but with people who aren't solely interested in Simon Cowell's pretty autotuned boybands. They're followed by people who listen to music. It's no coincidence that on facebook a long while ago, my younger brother said that he wished they'd go back to making their old music. I said that was rubbish, and that they couldn't, as they'd grown up and totally changed as a band. Evolved, if you will. He said "Everyone on the bus agreed with me." Right, so a load of teenagers (and noodle) don't like their new music. Everyone else (on the whole), oddly, does.
The National are followed by a good half dozen fans.
Liam is a dyed-in-the-wool teenager. Challenge his opinions about music at your peril.
You were another one, weren't you?
