One of the things I have been doing when I've been working on a project, is that sometimes I put on a track and just listen to it. I guess if I'm contemplatively melancholic or melancholically contemplative, or it just speaks to me. Sometimes I put several to mostly one on repeat.
I just switch to another gear and do abstract stuff like this. It's to sort of clear the air in my head to give the other bit a rest. It's sort of cool not knowing when it comes out.
