If I go to the website of almost every band on the planet with the intention of buying a pre-order vinyl album, an MP3, a ticket or a T-shirt, I am sent to four different stores, forced to enter my credit card four times, create four different accounts with companies I do not want to be associated with and deal with four different customer support centres chasing the delivery of my orders.
Try it yourself: I challenge you to actually buy something from the artists you work with, without wanting to hit your computer. Even better, try doing it on your mobile phone! It doesn’t work. The music industry has broken every rule in e-commerce; we have effectively broken the internet!
