Step-by-step explanation:
Bob Dylan's songs inspired others in the folk revival movement to explore new lyrical themes and styles. His work, dense with rich imagery and often addressing social issues such as civil rights and opposition to war, urged musicians and listeners to use music as a means for social change.
