Katy Perry, in a post on X this past Saturday afternoon:

I am deeply appalled and angry to see “Firework” used on the @WhiteHouse TikTok account as a backing track for video footage of military strikes. I did not approve this, I was not asked, and I absolutely do not condone it.

I wrote this song to be an anthem of hope, healing, and inner strength for people going through their darkest personal moments. To see a message of self-worth and upliftment weaponized to soundtrack destruction and violence is a complete violation of everything my song stands for.

My music is for bringing people together, not celebrating warfare.

She is the latest example in a long line of artists who have seen their work misappropriated in such a manner. You would think there would be some collective legal recourse available here.
