Abstract Most musicians, in their songs, portray their philosophical vision of life as could be seen in the case of Lucky Philip Dube, the black South African reggae musician. His songs show that he adheres to the principle of ethical humanism and portrays him as a crusader of social justice. Thus, this essay shows the link between musical art and law by examining the commitment of Dube’s lyrical composition in fighting for a just legal system in his society. This essay therefore, analyses some of his lyrical productions in order to expound on the philosophical ideas underneath the songs and how they tie with the search of an alternative jurisprudence and humanism in postcolonial discourse and the liberation of the subaltern. From the perspective of natural law theory, this essay postulates that Dube’s songs criticise the injustice of the legal philosophy in his society and quest for an impartial jurisprudence – that of equality and justice in his society.
