Sadly there are no tests to determine fastest longest or strongest when it comes to music. Maybe they should all compete by playing or singing like an exam.......in the olden days and even today before being allowed to join an orchestra you had to pass an audition and be of an acceptable grade....I doubt gaga or any of the others would make it. In fact it creases me to see orchestras or bands perform behind these "stars" where any member of the band has far more talent than the people they are backing.
In days gone by people worked their way up through the business and eventually their experience and talent was recognised. Sadly now people with limited talent make it big instantly by appearing on AI or X factor or similar shows. I say sadly because it is a sad indictment of us that we should condone and even encourage such a thing especially when most of us know people who can do so much better but do not get the chance.
