ard: I only heard/read that R’ Scheinberg zt”l allowed classical music, not all recorded music. He held that music which brings someone to increased simcha and/or dancing would be forbidden.
This is also what I was taught growing up, and what my family followed – classical music, or even slow music which won’t lead to dancing is permitted. Fast music, even acapella, is not allowed, as it can bring someone to dance.
