Ok, now that more people have posted long lists, I don’t feel so bad about mine ;)
German:
Some may be an acquired taste (PSB?, also I know that The Libertines’ is not everyone’s favorite – but it’s mine :). The Arcade Fire, even though I don’t listen to them these days that much, is decade-defining for me, as is Radiohead’s OK Computer (together with Nevermind, although for some reason it didn’t make this list).
American Football, yes!
