Either she can't control a crowd or they were DEAD as ****.

Well, they did come to see Coldplay , not her

The whole purpose of an opening act is to get the crowd in the mood. Have you ever been to a concert before?
You can see a few people jumping around and getting into the song, the rest are dead.

kinda ironic that the songs called RIP since the crowd is dead

I've been to many and it's hard for opening acts.

A. Either people will come late because they are only interested in the headlining act or
B. The music of the opening act isn't like the headlining act so it's hard for the people to relate

Yes. And I never care too much for opening acts.
