• "All Out Life" is a ferocious thrash-heavy rallying cry where Corey Taylor pleads to the listener not to treat the past with disdain. Rather than constantly looking for the next big thing, the Slipknot frontman is saying there's plenty of old music that should still be celebrated.
  
  Old does not mean dead, new does not mean best
  No hard feelings, I'm tired of being right about everything I've said
  Yours does not mean mine, kill does not mean die
  We are not your kind
  No excuses, I challenge you to all out f---g life
  
  Corey Taylor said: "It's not the date on the music - it's the staying power."
• Speaking to Beats 1 host Zane Lowe about the lyrical inspiration for the song, Taylor explained it's "about this toxic idea that unless something came out 10 minutes ago, it's not any good, and that bothers me."
  
  The Slipknot frontman went on to state that though he's a fan of new music, there's plenty of older material that he still listens to. He hopes this song will encourage people to get together and say: "You know what? Let's not talk about old. Let's not talk about new. Let's talk about what is. Let's talk about what's good, what's real, and get behind that and start embracing things that matter because there's history there and not just because it's the next best thing."
• Stylistically, the song's explosion of twisted heavy guitar riffs, punishing percussion and unrelenting pace harks back to Iowa, the masked metal rockers' heaviest album to date.
• The single's "we are not your kind" chant eventually became the title of Slipknot's sixth studio album. Corey Taylor explained to Kerrang:
  
  "I didn't think it would be anything more than a great chant at a concert. It was one of the things in my head that I could hear 50,000 people screaming at the top of their lungs, pumping fists. It wasn't so much that I thought it was benign or anything - it was definitely something that I thought, 'This could be something really cool' - but it took on a life of its own, and that's when I really started thinking about the phrase; about how it could be perceived."
• The We Are Not Your Kind record was titled after this song despite it not being featured on the album. Taylor explained: "It was just such a catchy song that it made sense to release it. But now, in context with the story that we're telling on (the album) we weren't sure if we were going to put it on there."
