a) Who puts up a 7 hour video unedited? Complete with the lunch break?
b) Yes, that music is owned by someone (probably several someones). Feel free to lobby for the law to change, but you don't get to use someone else's recent music without their permission. I think copyright overreaches a lot, and would limit it severely, but "I put someone else's recently-made music in my video" is definitely something copyright should cover.
c) For God's sake, edit the lunch-break out of the video and put it back up. And while you're at it, chop it into sensible chunks and put them up as separate videos - how hard can that be???
