To paraphrase the classic Chuck D quote, rock music is now CNN for white people. For one, bands are actually debuting songs on CNN, as when R.E.M. used the recent Anderson Cooper documentary “Planet In Peril” to premiere their new song “Until the Day Is Done” (see above video). Exhibit two would be the fact that every single new rock album has at least one political song: Even the Eagles got active on the anti-Iraq War title track to their new album, Long Road Out of Eden. Other prominent political songs from recent months: Arcade Fire, “Windowsill”; Bruce Springsteen, “Last To Die”; Kid Rock, “Amen”; Nine Inch Nails, “Capital G”; Tori Amos, “Yo George”; the list goes on.
