This is basically clickbait designed to capitalize on the new service.

With zero observation of what people want and how they experience it, he conducts a dry and pedantic assassination of the UI.

I've talked to 4 regular users today all of whom were having an enjoyable experience and expressing no concern about the UI - instead the conversation was all about what it was allowing people to discover and listen to.

The only person who had any discomfort with the service was a friend who hasn't used streaming before and was concerned about the ephemeral nature of what he listened to - I.e. Unlike with buying musing it's easy to listen to a lot of stuff and not make a connection with it to a particular place and time.

In any case unless you like pedantry, don't read this article - instead listen to some music.
