"Let's Roll" Neil Young (2001)

In the wake of 9/11, many songs were released that fed on the country's wounded patriotism, but few expected one to come from the same well as "Ohio" and "Rockin' in the Free World." Neil Young's ode to the doomed heroes of Flight 93, and titled after passenger Todd Beamer's final words, was considered by some to be a rallying cry for the retaliatory War on Terror. If so, Young's feelings about then-President George Bush Jr. had changed dramatically by 2006, when he released the subtle song, "Let's Impeach the President."
