Listening to music, I'll be doing one of the following.
2. Cleaning
3. Performing
4. Practicing for performing
While I 'can' listen to music while working, but I choose not to, it can be a distraction, and there is nothing worse that losing track of a thought process because of an external influence. I know lots of dev's that can, but not me. if I'm not knee-deep in code that I might listen to something, it depends on the level of concentration required.
I listen to music when I've got housework, again it's a distraction thing, but in the other way this time. I don't want to think about what I'm doing, it's mundane.
Sometimes I'll have to choose a song to perform to, s If I have enough time, which I never do, I'll try to edit something together, and then there are the hours of practice... I often end up hating the song afterwards....
