Cover art for Innocence (Live Intro) lyrics by Airborne Toxic Event, The

I think the term "innocence" in this song is used to portray an actual person or girlfirend. He got dumped. He lost a very virtuous girlfriend. Thus he lost his optimism in life.

Well, I lost my innocence today I could feel her in my bones My bones, my bones, my bones My blood, my blood, my blood, my blood

I do not think "virginity" could be symbolized by "innocence" in this song. It just doesn't connect with the first half.
