  In this note we show that the entropy of BPS, rotating, electrically charged
AdS$_7 \times S^4$ black holes can be obtained by an extremization principle
involving a particular combination of anomaly coefficients of the
six-dimensional $\mathcal{N} = (2, 0)$ theory. This result extends our previous
finding for BPS, rotating AdS$_5 \times S^5$ black holes.
