This is the kind of safe space I am proud to provide for the weirdos of the world.
I’m going to play the middle and say Mr. Brightside is an objectively better song, but I prefer When We Were Young. Brightside has a more memorable video —that pretty girl and sweaty Eric Roberts!— but I had to sing When We Were Young 1,001 times while obsessively playing Rock Band in 2008, and I’m now brainwashed into loving it.
(Same thing happened with Weezer’s Say It Ain’t So. I didn’t give a shit about Weezer —aside from Buddy Holly— before Rock Band.)
