Consider this following song, Presence of Mind by Dynazty (I have marked it to the point relevant to my question). At this point, a male speaks over the song, and these are part of the song's lyrics. However, it is not, strictly speaking, singing.
Suppose a woman were to perform that part of the song (or any other song with such a part to it). Is this acceptable for a man to listen to because it is not singing, or unacceptable because it is analogous to/very close to singing?
Note: The genre of song is heavy metal and may be considered disallowed by some authorities for that reason, regardless of who is singing it. For our purposes, assume an arbitrary permissible song.
