I use the age-old (well, relatively so :)) equation of headphones and electronic music. It gets you into that coding trance that is so helpful for actually sitting down and getting work done: just put on fast-paced electronica/trance, open up TextMate/emacs/etc, and allow your focus to zero in on exactly the problem you need to address at that moment.

I second that, albeit I use my studio monitors instead of ear buds as I live by myself. I listen to http://mugasha.com - a startup focusing on bringing EDM music sets online in an easy to listen way - instead of 2 hour sets, they are broken up by listing.

disclosure: one of their founders is an online friend and will be my hotel roommate at SXSW later this week
