King of the jingle is cult star of Japan's railway

TOKYO - Minoru Mukaiya is one of the world's most played musicians, with millions of people across Japan listening to his songs every day - but most of them don't even notice.

Mukaiya is a composer of Hassha Merodii or train departure melodies, short jingles that whisk commuters on their way at some of the world's busiest stations.

Almost no one would know his most famous track by name, a catchy electronic ditty broadcast for departures from platforms three and four at Tokyo's Shibuya station - the world's third busiest - but millions have it on their brains for hours after their commute.
