On rewriting… When you're working on an album, is it more that you write way too many songs and pick out the best ones to rework some more until they're just right, or do you write close to the right amount of songs and just work hard on them until you get them into shape?

On collaboration… How do you avoid a bad collaboration experience? (Have you had any of these? What do you look for in order to make it more likely to be a good collaboration experience? What things are good things to do? What things should be avoided if possible?)
