We discuss the physical spectrum for W strings based on the algebras Bₙ, Dₙ, E₆, E₇ and E₈. For a simply-laced W string, we find a connection with the (h,h+1) unitary Virasoro minimal model, where h is the dual Coxeter number of the underlying Lie algebra. For the W string based on Bₙ, we find a connection with the (2h,2h+2) unitary N=1 super-Virasoro minimal model.
