Y2Kessler: Audiogarden or Soundslave?

If you're a Chris Cornell fan then you know he went from Soundgarden to Audioslave. But did he write a song about it? That's what some people speculate what I Am the Highway was written about. Other people think it's written about him divorcing his ex-wife. Regardless of it's meaning, this hit in 2003 made it up to number 2 in the mainstream rock tracks!
