Music's too important to me. It'd be like giving up breathing or eating. I don't even think I could stop thinking about music if I tried. I've constantly got music running through my head and ideas for songs or tapping my feet and hands.
Guess, as long as I've got a working brain I'll never be without music. If I can't find something to make an instrument out of or at least something I can drum on, I can just close my eyes and listen to all the old songs stuck in my brain.
