Final track on Beyoncé's "Cowboy Carter" (4)

I believe the answer is:

amen

(Other definitions for amen that I've seen before include "Word at the end of a prayer" , "Churchgoer's assent?" , "Conclusion of prayer" , "Put name to end of payer" , "Word of approval" .)

I've seen this clue in The New York Times.
