Look what you made them do: All the Taylor Swift references from the Senate's Ticketmaster hearing

Washington — There was no shortage of bad blood between senators and ticketing giant Live Nation Entertainment at a Senate Judiciary Committee hearing on Tuesday, with lawmakers grilling the top executive from Ticketmaster's parent company over its business practices and last year's debacle involving ticket sales for Taylor Swift's upcoming stadium tour.

The proceedings also allowed some senators to prove they — or maybe their staff — were well-versed in the pop star's discography.

Joe Berchtold, the president and CEO of Live Nation Entertainment, must have known he was in trouble when he walked in, and quickly found himself fielding barbs from senators who questioned whether the 2010 merger of Live Nation and Ticketmaster was stifling competition in the live events industry.

"The fact of the matter is Live Nation-Ticketmaster is the 800-pound gorilla here," Sen. Richard Blumenthal, a Connecticut Democrat, said. "This whole concert ticket system is a mess, a monopolistic mess."

Describing the effects of Live Nation's power and reach, at least one witness suggested Live Nation and Ticketmaster should be broken up and never, ever get back together (like, ever).
