Couple of things:

  • the error message - you probably have the Mopidy service also running and that’s taken the HTTP port already. Read the documentation section about running Mopidy and chose a method. Most people will want to run the service.
  • it has not hung. Mopidy is running at this point. Its waiting you to connect with a client so you can give it commands. Clients can be Web clients or MPD clients if you also install Mopidy-MPD. Lists of clients (frontends) are available at http://mopidy.com/ext

Thanks for the advice and information.
