I just noticed that, after a two-year hiatus, my favourite streaming radio station is back online!
bluemars.org broadcasts a blend of ambient spacemusic that was the aural backdrop to many an hour of coding when I was at university. I find that it's great music to work to -- energising but not distracting, not intense enough to steal my concentration, but aggressive enough to keep me focused. Perfect background music for a busy day.
All you need now is a busy day... :)
