Haha @Guy! Loving the Spinal Tap reference there!
I think you have a point, as does Jessie. Yes, there are a lot of women who use their bodies to sell their music. Well, I say 'their' music, but it's usually written for them. Most of the female songwriters I like wouldn't dream of showing their bits and bobs: Emiliana Torrini, Laura Marling, Kate Bush, KD Lang. All the best ones wear proper clothes!
