I experienced this on another level while working retail at a musical instrument store for a few years. People would pick up any instrument and play whatever they wanted for however long they wanted-- at whatever volume they wanted. Although some people are quite talented, most are not. One lady would sit at the piano for hours, playing the musical equivalent of nonsense. Around that same time, I had my own home recording studio and sometimes wound up recording musicians that were on the scale of bad to downright terrible. If I reacted negatively to the sound they made, that would only make them want to re-record it, which meant I'd have to hear it again. I quickly learned how to keep a straight face and mentally treat the music like background noise or focus intently on the parts of it that weren't too bad.
