Reply To: Anim Zemirot and Shabbtai Tzvi

Some people limit the use of An’im Zemiros for the same reason nusach Ashkenaz limits the use of Ho’aderes veho’emuno — because of its extreme kedusha. The way it’s said in some shuls, at the end of davening, with half the people talking, folding their taleisim, or otherwise not paying attention, is truly not appropriate; if a rov sees that this is happening he should either move it to after shachris or stop saying it until people get the message.
