Sometimes working on the house can be a bit mindless. Painting, mudding, sanding, gluing, framing. They all take my attention, but not much thought. I am writing songs and vocal melodies while I build. I'll replay some guitar riffs in my head until I like the structure. Or, play some prerecorded stuff from a friend... on my phone, until they're memorized... rebuild sounds into a structure that I like. Time can fly when I'm thinking about music. And hey, I just got 2 birds when I arranged a song.
