"Tammy's Song (Her Evils)" revolves around two girls cheating on their boyfriends after discovering they were unfaithful, and eventually sleeping with each other because they can't trust men . "Keisha's Song (Her Pain)" is about a prostitute who seeks comfort and control, only to her demise . Lamar explains that Section. 80 is for people born in the 1980s until now as he dwells on a variety of subjects, such as referencing Ronald Reagan and discussing how the crack epidemic occurred in the 80s . He explains how this is part of the reason drugs are popular for his Generation (e.g. drug dealing and drug addicts .) "A.D.H.D" addresses the high drug and medication tolerance of people born during the Reagan era .
