Imagine Dragons is great pop music. Just like 'fun.' is good pop music. If you don't like pop music that's fine (I don't either), but even then you should celebrate that they are taking airtime away from the Taylor Swifts, Beibers, Rhinaannahanhans and other corporate boardroom produced, xfactor winners, and autochunes of the world.
Don't get me wrong. They're completely commercial, but so is Sasquatch BROUGHT TO YOU BY ESURANCE AND KOKANNEE, PRODUCED BY LIVENATION. Just because someone's making money off of it doesnt change the quality of the music/festival.
A good litmus test for douchebags last year was how quickly they brought up 'fun.' and scoffed at them. Imagine Dragons will be that band this year.
Unrelated, but every girl at the festival will be at imagine dragons.
I would buy all of this if they were actually good pop music, as you say. I could probably name 5 current pop artists that I would rather see at the gorge this year in a heartbeat (Alex Clare, Willy Moon, Rihanna, Ellie Goulding, Adele...). Plus they look like hipster/hobo Nickelback.
