Why don't girls make good music?

[scotty34]

This is an obvious corollary to the girls and humour thread. Really though, I can't think of a single timeless classic created by a female. Pretty much any great song of its time was written and performed by a male as far back as music goes. On those commercials for "50's Classics" or other similar collections they will often include a few female songs, but I really don't think any of them can stand the test of time. They are simply included to be politically correct, or some equally dumb reason. Maybe I'm just a really sexist person, but seriously, do females make any REALLY good music? Give me some examples please
