Rachel Platten Speaks Out About 'Fight Song' Being Played at Inaugural Balls

The hit single was widely regarded as Hillary Clinton's campaign anthem.

The singer took to Twitter on Friday night to tell her fans that she did not give permission for the band the Piano Guys to cover her music.

"While I respect the office of the President and the peaceful transfer of power, I want to make clear that at at [sic] no point did the Piano Guys ask for permission, nor did I or anyone on my team know of, approve or endorse their decision to play Fight Song tonight," she wrote.

After the Piano Guys played "Fight Song" at the Freedom Ball and the Liberty Ball people questioned on social media whether the performance was meant to mock Clinton.
