A misleading term used to describe performing music; it implies that it's a game. English is one of the only Western languages that use 'play' for music. When fans see a band smiling on stage, they see people enjoying the performance. They do not see the roughly four hours of preparation that goes into each hour of performing, including publicity, rehearsal, travel, and multiple load in/load out/set up/teardowns. Being an entertainer is rarely entertaining.
