Forgive me if I misread you, but I would think that Ticketmaster would hate bitcoin - an open financial transaction network. My take on Ticketmaster is that they unashamedly work to maintain a monopoly to charge highly profitable fees on every transaction.
I meant that Bitcoin would make ticketmaster not needed. Ticketmaster ia basically a monopoly when it comes to ticket sales. Bitcoin would let venues go around ticketmaster and cut out a very expensive middleman in the ticket buying process.
