• Here, Eminem reflects on his regrets and transgressions throughout his career.
  
  It seems to be the reoccurring main theme
  The s--t I would daydream as a kid, I was eighteen
  I went from an irate teenager to still raging
  
  Marshall Mathers is particularly frustrated with his Slim Shady persona whom he created when D12 was formed. His alter-ego, as described by Em, was the evil side of him, but it resulted in him rapping about such regretful topics as killing his wife Kim as well as verbally torching his mom to the extent that she filed a defamation lawsuit because of his lyrics about her.
• The hook is sampled from the 1994 song "Zombie" by the Irish rock group The Cranberries. The words for the original 1990s hit are about the devastation created by the bloody civil conflict between Northern Ireland and the United Kingdom. However, Eminem reinterprets the lyrics to reference the dark and angry thoughts that his alter-ego has voiced.
