So, you make some music and after a while when you google your artist name you find yourself (or your music at least) on a bunch of blogs

what's the etiquette here? Do you mail the bloggers and build up a relationship/rapport?

do you mail them and tell them they have incorrect titles? tell them to put a link to your myspazz?
tell them to take down your mp3s?

or just feel a little smug and/or forget about it?

I'm a novice in the blogosphere - tips please
