Studying my Bounce via Analytics

[dlyricist]

Folks,

I am trying to analyze my high bounce rate of 62% at my site dlyricist.com and found that traffic source from "Direct/None" gives nearly 70% bounce rate and yet more time is spent on site than average and more pages read. After digging in Google groups I've found that they describe "Direct/none" traffic as People that type the URL directly in their address bar /People that click on javascript links look like direct visits because javascript links don't give a refferrer etc.
However when I type in my own URL, can part of that traffic be me tweaking away? or spiders crawling explaining the the greater time spent on site?
