Simple truth is, in my case, as far as protecting my material goes. I'm just too damn lazy.
As you could appreciate Rob, by the time I've written, performed the entire track and then produced it, there's simply no energy left to go fill out copyright forms.
Would definitely be worth it if I wasn't such a lazy a-hole, I guess I imagine if a time ever arose where someone decided to steal my material I'd just track em' down and beat them up, hehehehe just joking.
