I would beg everyone, everywhere, to cut back on background music. Keep it QUIET, at least, or intermittent. I'm hard of hearing, and background music reduces my chances of getting it all in one listen. I rarely find time for one, let alone MORE than one, viewing (hearing) of any video that contains information I want to learn. Ken Burns (you are in good company, @sethlinson!) ruined his Lewis and Clark documentary by incessantly playing the same background song. I had tolerated Ashoken's Farewell in his Civil War doc, but by the end of six hours of Lewis and Clark and the same song playing endlessly (mute button won't stop it), I was scarred for life by background music.
