Yeah, that was sure cute, though I'm a little sorry they didn't do more with it. Changing gender doesn't actually influence the plot in any particular way. The "curse" could have been simply the music in their heads... becoming women is largely incidental. They don't examine their conditions or reflect on the opportunity for perspective or find any particular weakness or advantage... kind of a missed opportunity. But like I say, beggars can't be choosers. It's a great find anyway.
Still, Tran4of3 did a short comic of his own along the same lines a few years ago that handled the premise with far more gravitas. It's
here, if anyone's interested.
