On a slightly off topic note, rockstars need a lot of skills to be successful. As you said it isn't only about music (I beg to differ that it does not relate to music at all), but a lot of different stuff. A rockstar has to catch the attention of millions of people and that is a skill which not everyone can master. This actually relates a lot to college professors. You might have noticed that there are some professors which just fail at catching your attention even though they might be expert in there subject while there are some which may not be the best in content but just catch attention of a huge student body in a lecture hall.
