Culturalappropriation - Tumblr Posts

I found out that one of my songs that I’m required to sing as part of Choir is a traditional black church song. Not sure if I should do smth like tell the professors abt it or should I stay quiet? Professors are two old white ppl btw and 90% of the Choir is also white. It feels sort of like we’re appropriating a culture that doesn’t belong to us.
