How have the recent changes in the music industry been affected by the principals of supply and demand

The Telegraph

While I may have had to adjust my research question to make my topic more broad and applicable, I have learned much about the way the music industry has been shaped by supply and demand in recent years. Firstly we have seen a large increase in the price of concert tickets because of the decrease in the sales of complementary goods. We have also seen much more broadly how streaming services have impacted the music industry. The increasing popularity of R&B/Hip Hop, the shortening of songś length, and lastly why the industry is heading in the direction of streaming. All of these trends are closely related to supply and demand.
