Nice and Clean OR Down and Dirty?

[bambooneedle]

What are good nice and clean or down and dirty EC numbers?

For example,

Would you classify Last Boat Leaving, Alison or (What's so Funny 'Bout_ PLU as down and dirty songs?

Would you classify Spooky Girlfriend, Complicated Shadows or I Want You as nice and clean songs?

So, show some proof... which are better?

Sometimes when he tries to be nice and clean, he almost comes across like some damn upper class statesman or something...
