As Michael mentioned after seeing it, it would be great to see a chart of sustainable music careers (rather than gross sales of recorded music) to see if there’s been any change at all in the music business.  In other words, how many artists are making a profit and enough money to live on (say $30k per member) across the entire business.  I think that’s the greatest challenge these days – not to break through huge but to break through enough to make a decent living.  Onward and upward!
