Princeton University defines enthusiastic as “having or showing great excitement and interest.” Bob Marley’s “Jammin’” epitomizes enthusiastic tone. The repetition of ‘jammin’” exemplifies the singer’s excitement and interest in having fun- “jamming”. “No bullet can stop us now,” implies the singer is unstoppable in his desire to jam. The verse highlighted in blue references the Holy Mount Zion. This reference to such a holy place, as well as other holy references, tells the audience ‘jammin’ lifts Marley into true happiness and excitement. The musical accompaniment reinforces the enthusiastic tone with upbeat and smooth guitar, drum, and synthesizer melodies.

While the song choice certainly words, I was looking for more than a single line and a chorus for word choice and interpretations. Why does "Jammin" equal enthusiastic?
