  We present new results of our studies of soft-gluon angular ordering effects
on the evolution of both collinear and transverse momentum dependent (TMD)
parton distribution functions, and discuss their implications for precision
predictions of Drell-Yan transverse momentum spectra at the LHC. Our method is
based on the parton branching (PB) approach. We compare this with the
implementation of angular ordering in the Kimber-Martin-Ryskin-Watt (KMRW)
approach and with the Collins-Soper-Sterman (CSS) approach. We illustrate
numerically the effects of different ordering scenarios ($p_{\bot}$, angular
ordering), including definitions of the soft-gluon resolution scale and scale
in the running coupling, on the theoretical accuracy of predictions in the low
transverse momentum region of Drell-Yan spectra measured at the LHC.
