“Cherrybim has claimed before that R’ Moshe was mattir’
I didn’t say Rav Moshe was matir. Rav Moshe holds that listening to music, outside of a mitzvah event, is forbidden all the time due to availus for the bais ha’mikdash. I indicated that Rav Moshe’s reason to permit music the rest of the year to people who need it for psychological reasons, such as, to calm their nerves, could perhaps also be applied to those who need it during s’firah for psychological reasons.
