You will require this licence if you operate a business where you intend to play sound recordings (such as CDs, tapes, digital downloads) in a public place, exhibit music videos or use sound recordings for telephone on hold that are covered by copyright.
You would obtain a licence from OneMusic Australia depending on the type of business or organisation you are operating and this covers the rights of music rights management organisations in Australia.
