It's interesting to know this. As you said, this job has very high requirements. Most of us are not able to do it because we are not talented enough. :)

Not sure how many buskers can afford to travel around the world, but yes, it’s a job as long as you make a living from doing it, otherwise, it’s just a hobby.
