  We show that the semiclassical entropy of $D$-dimensional rotating
(an)isotropic black holes with planar horizon can be successfully computed
according to a Cardy-like formula. This formula does not refer to any central
charges but instead involves the vacuum energy which is identified with a
gravitational bulk soliton. The soliton is obtained from the non-rotating black
hole solution by means of a double analytic continuation. The robustness of the
Cardy-like formula is tested with numerous and varied examples, including AdS,
Lifshitz and hyperscaling violation planar black holes.
