Radio observations are a unique window to explore the mystery of cosmic
magnetism, from the Galaxy to cosmological ages. By tracing synchrotron
emission below 200 MHz with unprecedented sensitivity, the LOFAR
telescope is providing us with the most detailed image of the magnetized
Milky Way that we have just started to study. In this talk I will
present the progress of my MUSICA project. We have contributed to step
forward in the understanding of the radio sky, highlighting with first
statistical results the complex coupling of the multiphase interstellar
gas with magnetic fields in our Galaxy. Our observational results and
numerical models of the turbulent, multiphase, and magnetized Galaxy are
preparing the ground for the interpretation of next-generation
radio-telescopes such as NenuFAR, LOFAR2.0, and the Square kilometer Array.
