Popcorn time was popular because it was way better than any of the legal alternatives. You just had to open it, type the name of the movie/series and you probably could start watching. You could also do this in the legal alternatives, but the chance of actually finding what you were looking for was pretty small.
Here I don't really see how this is better than Spotify/iTunes/Amazon Music.
