I'm a great fan of Judy Small. A lot of her material is written from a definitely feminist perspective, and sound systems have been known to go unaccountably 'dead' on her while singing material like 'The I.P.D.' or 'Montreal, December '89'. (Sorry, no blickies, Supersearch isn't working just now.) But she has also written songs from a male perspective.

As has been said before, it all depends on the content of the song.

On the other hand, there seem to be traditional songs that were only sung by men / women, and only in male / female company. Ailie Munro, in her book 'The Democratic Muse', gives an example from Glasgow of songs that were only known to young women and never sung in mixed company, only on hen nights and the like. They were probably about a subject no well-behaved girl would talk openly about in those days - or maybe it was just for the fun of it!
