Does anyone know of a blog system I can add to a site I am making? there will be a total of 5 blogs. 1 for each band member. i don't want to have other people sign up and get a blog, i just want each band member to be able to have one that they can update and their fans can read...

is there anything like that out there that isn't hard to add to a site?

I think WordPress MU would do the trick:
http://mu.wordpress.org/

If you only have 5 blogs, you could always just go with a normal WordPress install. If I were doing the system I'd just have one WordPress instance and just separate the authors into different sections. You could also make 5 different WordPress instances, which would take more space, but might be a little easier to customize for each author. You could also go the WP MU route, but it's just a little harder to set up, and offers less flexibility for the authors.

did you heard of buddypress.org the new social platform of wordpress? if not check it may be it can help
