It depends how the songs like "wee cooper" are presented, it couldbe used in school to discuss the subject of wife beating.
is it better to discuss the song than pretend it never happened and not sing it.
there is more to this song than just violence, it can be discussed as how two people should not behave in a relationship, it is all about how the song is used and how its presented, it can then be pointed out that the message is wrong, that violence does not sort out laziness

WEE COOPER OF FIFE

There was a wee Cooper wha lived in Fife,
Nickety, Nackety, noo, noo, noo,
And he has gotten a gentle wife,
Hey Willy Wallacky, hoo John Dougal,

Nickety, Nackety, noo, noo, noo,
For the spoiling o' her comely hue,
Hey Willy Wallacky, hoo John Dougal,
A lane, quo'Rushity, roue, roue, roue.

She wadna card, nor she wadna spin,
Nickety, Nackety, noo, noo, noo,
For the shamin' o' her gentle kin,
Hey Willy Wallacky, hoo John Dougal,
