Trump's piano guy and cello player just trolled Hillary fans, bigly

In the event supporters of Hillary Clinton haven't had a bad enough day, Donald Trump's camp just rammed the message home one last time, in the cruelest, most absurd way possible.

At one of the many inaugural balls on Friday night, The Piano Guys—yes: The Piano Guys—decided it would be the perfect time to troll the opposition. Because who doesn't love punching the poor person sobbing in the corner?

So, The Piano Guys made it their business to play the summer anthem of the Democratic National Convention and a de facto theme of the Hillary campaign, Rachel Platten's empowering "Fight Song." If the melody doesn't destroy your bleeding soul, the smug smiling face of cello player should do the trick.

To top it all off, Rachel Platten is pissed. Apparently she didn't agree to any such troll behavior.

The Piano Guys, meanwhile, reckon it is all a massive misunderstanding.

"Our performance tonight, which combined 'Fight Song' and 'Amazing Grace' had nothing to do with Hillary Clinton or politics," the group said in a statement emailed to Mashable. "We chose to perform our version of 'Fight Song/Amazing Grace' -- it was not endorsed by Rachel Platten. We love Rachel and we love her song."

Make up your own mind. Trolls, pictured trolling:
