• This song appears to be about Kurt Cobain, Dave Grohl's bandmate in Nirvana. Here's the evidence:
  
  "Resolve" - This could mean coming to a final decision on Cobain's Death, or resolve in musical terms means going from a harsh, disagreeable combination of sounds to a close correspondence of sounds (ie. Nirvana's Distortion to Foo Fighter's Harmonic Sound).
  
  "Swingin' from the chandeliers" - in Nirvana's "Come As You Are" video, Cobain is Swinging from the chandelier.
  
  "I remember watchin' you, once upon a time, Dancing from across the room" - As Nirvana played, all Dave Grohl could do was watch Kurt dance about the stage while he was stuck behind his drums.
  
  "In another life" - for Grohl, so much has happened since Nirvana it seems so long ago.
  
  "Lookin' back to find my way, never seemed so hard" - after Kurt's death, Dave found he had some hard decisions, as Nirvana was no more.
  
  "Yesterday's been laid to rest" - Kurt's been laid to rest."Changing of the guard" - Dave felt he had to look out for Kurt, now he is saying that is someone else's role (God).
  
  "I would never change a thing, even if I could" - Dave wouldn't have it any other way because he would not have gotten the chance to write songs and sing. It could also mean he wouldn't change a thing about when him and Kurt were together.
  
  "All the songs we used to sing, everything was good" - Dave used to do some backing vocals on Nirvana tracks, doubled up with Kurt's voice.
