According to Robert Christgau, "The Lost Tapes" abandons the thug persona of Nas' previous work in favor of more sensitive, nostalgic, and autobiographical lyrics. "Slate" magazine's David Samuels interpreted "a message that begins with a rejection of the materialism of his ... rival Jay-Z" and "the home truth about how most kids in the projects feel about the real-life gangstas who live in their neighborhoods", citing "No Idea's Original" as an example. "New York Daily News" writer Jim Farber commented on his lyrical observations, "Nas focuses on linear scenarios and on human motivations ... "unlike many hard rappers, Nas' tales of ghetto horror are not covert boasts but expressions of true fear". Farber took note of "a cinematic tale of self-destruction in 'Drunk by Myself,' and a compelling autobiography narrated from the womb in 'Fetus.' "
