I think the answer is that any instrument played well is listenable to, yes even banjos, accordeons, Scottish bagpipes and gurdies, and I have heard virtuoso players on each of these that can send a shiver up the spine.   What is painful is to hear someone in public playing out of tune/badly, etc. It would be better if they went back and practised more or listened more to themselves before inflicting others to the sound.
