"soul"dier

i've got that killers song in my head "all these things that i've done". the same words keep running through my mind, probably because they're the only words that i actually know. sad. "i've got soul, but i'm not a soldier; i've got soul, but i'm not a soldier". over and over and over again it plays in my head. what does that line really mean anyway? i've got some ideas, but i'd like to hear others. i'm open to philosophical interpretations as well as silly ones, so throw them out there.
