Today, music users use 『stock』 and 『flow』 values ​​differently. Stock and flow are terms used in the financial industry. When applied to a general business, stock actually means holding things etc. Stock value means “value generated from holding”. On the other hand, the flow is always changing and not fixed like the flow of the river. Products and services can be divided into those that hold value and those that change. This stock value and flow value are sophisticated and difficult ideas, but when applied to the music business, it is easy to understand.

 Originally, music flowed momentarily and could not be possessed, and there was only flow value. The ability to confine and hold the music on records, cassette tapes, music CDs, etc. has created stock value. Users tend to find stock value in CD holding itself.

Then, think about the music delivery business. When buying a music CD, the user recognizes the stock value. On the other hand, some people may want to pay for the flow value that they only have to listen to music without finding a value in particular.

 The same music distribution service addresses the need to place music CDs as sound sources and support by holding music CDs of favorite artists. On the other hand, streaming on the Internet finds the value of flow at the moment the music flows. Even if you don’t own it, you can play your favorite songs when you like. The music is the music that you want to listen to at that time, and it is a way of thinking that you do not have to bother. It can be said that in the music industry, users have begun to use stock value and flow value properly.
