Taylor Swift Pulls Plug on Rock in Rio Livestream Fans Pissed

Taylor Swift pissed off people from around the world Friday night, when she pulled the plug on a livestream of her concert at the very last minute.

Taylor performed at Rock in Rio in Vegas, along with Bruno Mars, Ed Sheeran and John Legend. Yahoo! Music made a big deal that it would livestream the entire concert, including Taylor's set.  But just before Taylor went on, she had a change of heart and nixed the livestream.

Fans were irate, some of whom stayed up all night so they could watch her sing.

Taylor famously goes to great lengths to protect her music, but a lot of fans think if she really had a problem with the livestream she shouldn't have signed up in the first place.
