As PaNiCAtTaCk related the granting or retracting of the piano-playing privilege was a source of contention in congregations over and above M.S. or elder appointments.
Old Sister McKinney in the black congregation in Little Rock never forgave the young upstart elder from New York who took away her piano privileges for an "unsubmissive attitude". She used a slang, derogatory name to refer to Bro. Perkins. Sister McKinney had been the "Company Servant" in the Little Rock East Congregation in the 40's before qualified brothers became available.
Sister Hilliard in North Little Rock never got over having her piano privileges revoked when her and her elder husband separated "unscripturally" never to divorce or remarry.
The record/cassette/CD playing was certainly less spontaneous, but the regulating of piano-playing privileges in many congregations was a real pain in the proverbial ass. Balancing piano skill, nepotism, "spirituality", congregation politics, etc. was an impossible task.
