Ladies and gents, let me preface this by saying I am no way affiliated with this artist; but I did purchase it (because sweet mother of god it's cheap.) There's some great mood music for tabletopping in the form of a soundtrack written/composed by Austin Wintory available for downloadable purchase right now. Four bucks gets you the whole album, and you should totally jump at the chance. Dive on it, GMing brethren.
