I have always found it pretty therapeutic to have some good tunes playing while I paint, or do any work for all that matter. But of course, being a child of the 21st century, I am always looking for bigger and better ways to entertain myself enough to be able to slip into a somewhat mindlessly efficient state where I do not realise how much work I am completing. For math, it was always Idioteque by Radiohead and art always changed depending on the daily mood. I recently stumbled upon some interesting looking online television on the Vice Magazine TV site. Looks like they have some interesting programs to watch, or just listen to. Sounds like a good substitute for an audio book.
