Live Nation isn't just a tour promoter: it's a company that owns, manages and controls venues, ticket merchants, music labels, concert production, resellers and so much more... and some artists reckon it's tearing the Australian music scene apart.  Plus, racism and division sparked during the Voice referendum is still being felt one year on. And does listening to music help you work? It's a divisive one, and your answer might come down to your personality type and level of arousal (which doesn't mean what you think).  Guests:  Avani Dias, reporter, Four Corners Dr Anna Fiveash, cognitive psychologist, Western Sydney University
