Exactly. If you're even slightly involved in the music world and you play and instrument you've always got something going on. The only musicians i've ever known have been in local bands and even they eat, breath and sleep their music and are always working on it.
I'd imagine Metallica is very much the same. It's been their life for the better part of 30 years now.
