Modern Japanese music has been influenced by Western genres like rock, pop, and jazz. Some common Japanese music terms include "aidoru" referring to pop idols, "gagaku" meaning traditional court music, and "kayokyoku" referring to pop music. Popular Japanese rock bands like Dir En Grey and An Cafe have incorporated Western styles into their own music. J-pop is Japanese pop music that sounds similar to American pop songs. J-rock copies the psychedelic rock style without drugs. Music festivals in Japan include Fuji Rock Festival, the largest, and Tokyo Music Marathon where live music is performed for free throughout the city.
