requested an iPod with In Your Honor in it during the incident. As Grohl was moved by this action, he decided to "write something just to dedicate to him that night because he definitely seemed like a hero", and later promised to include the instrumental on the album. The album version features Kaki King, whom Grohl invited to record the song as she was visiting Studio 606.

Grohl added that there was a bigger focus on melodies even in heavier tracks such as "The Pretender", "Let It Die" and "Erase/Replace", and that album closer "Home", a ballad featuring Grohl on the piano, was "the best song I've ever written". The songs of the album are noted for their changing dynamics – with "middle
