A talk I gave at Loyola University on the history of the music business is now available online here.
It's about an hour long and is a distillation of a number of things I've talked about over the last few years.
(Note that I am incorrectly identified as the "co-founder of Rhapsody Music". While I was the product manager and wrote the initial business plan, I was neither a founder of TuneTo.com (where the product and technology were born) nor a founder of Listen.com (which launched Rhapsody 1.0).)
UPDATED: The last, important thing? "WEAR YOUR EARPLUGS." (And disabled the auto-start...sorry about that!)
