Why rap music is a oxymoron?

The term "rap music" is not an oxymoron. An oxymoron is a figure of speech that juxtaposes two contradictory terms, such as "jumbo shrimp" or "bittersweet." Rap music, on the other hand, is a genre of music that incorporates rhythmic speech that is delivered in a poetic or storytelling manner. The term "rap" itself is derived from the verb "to rap," which means to talk or converse in a quick and rhythmic way.
