Ah, so many songs to choose from. It could have been “Road to Joy” by Bright Eyes or “Gimme Shelter” by the Rolling Stones (though that’s about Vietnam and last night President Obama swore that Afghanistan is not Vietnam, right?…) or “It’s a Hit” by Rilo Kiley. But we’ll save all those for another day. I think I’m going with “Intervention” by Arcade Fire. (That’s why it’s sporting the bold, see.) I wrote half of my next book, The Hole We’re In, listening to this one, by the way — if you could wear out a digital file, I would have. I remember hearing that song for the first time in a hotel room in Santa Monica several years ago and thinking that I needed to get on writing better books.
