How do I know if I am playing music owned by JAMMS' members?

Because JAMMS has the right to license an extensive repertoire of sound recordings owned by hundreds of producers, labels and companies worldwide, invariably sound recordings from JAMMS repertoire will be played at some point in time. JAMMSí repertoire covers all kinds of music ranging from reggae, dancehall, rocksteady, pop, rock, rap, hip hop and jazz; to music in TV programmes, films and jingles.
