Ok, so I said that six sigma means quality! What does that imply? Well in general terms six sigma quality means that out of 1,000,000 occurrences no more then 3.4 have defects. Looking at it from the music industry point of view it could mean that:

For every 1,000,000 people that hear you sing all but 3 want more!
For every 1,000,000 concerts that you perform all but 3 sell out completely!
For every 1,000,000 albums you sell all but 3 customers want to buy more of your albums.

Do I need to go on? I think you pretty much have the idea! Think of the possibilities. A large audience full of very happy people or customers. How much money you would be making? Its mind boggling!
