Two different approaches to the calculation of the wave spectra of magnetized strongly coupled liquid One-Component Plasmas are analzyed: the semi-analytical quasi-localized charge approximation (QLCA) and the angle-averaged harmonic lattice theory (AAHL). Both theories are benchmarked against the numerical evidence obtained from molecular dynamics simulations. It is found that not too far from the melting transition (G >~100), the AAHL is superior to QLCA, while further away from the transition, QLCA performs comparably or better than AAHL.
