Irving Azoff's twitter-tantrums

Live Nation's temperamental executive chairman has been posting some not-so-flattering tweets about Billboard business columnist Glenn Peoples ("u r a jerk"), rival concert promoter Randy Phillips (implies he's a habitual liar), and music fans in general ("so if you want ticket prices to go down stop stealing music"). From Speakeasy:

Among those offended by Azoff's implication that artists would lower their ticket prices if they could sell more recordings was blogger Mario Lavandeira, better known as Perez Hilton. "I Love artists," Hilton wrote in response. "But blaming concertgoers for ticket prices is wrong. Wrong attitude. Wrong approach. Wrong everything!" Azoff managed to keep it civil in his response to that critique ("not blaming. Just pointing out that it's the only way an artist can pay their bills anymore").
