I was indoor cycling to spinning class once and my instructor played a CD with eletronic music for the exercises, and one of the songs was an ayumi hamasaki remix (from DJ amaya, which is also an user here on AHS)! And she one day said that ayu was like madonna (in terms of being famous) in Japan, and that her songs were really good.

I was quite impressed, as i'd never expected someone at random would ever appear in the city I live, and spread the ayu love like that
