Cover art for Headspace lyrics by Velvet Revolver

To me, Weiland is saying that he is just a man, and he can't be perfect all the time, and interviewers for magazines are always getting him wrong. Basicly it's messing with his head:

'Don't let any of those fuckers in my headspace'

but IThinkIKnowLyrics has a very good point... Bravo
