These Days by Foo Fighters (2012)

Dave Grohl says "These Days" is his favorite song he has written. They performed the song in tribute to people killed at Pukkelpop in 2011 when they themselves played there in 2012. Rolling Stone mag listed it as one of the best songs of 2012. In all honesty, this might be the song of the year and the best thing Foo Fighters has done.
