"Hi ho, hi ho, it`s off to work we go.." the song from Snow white sung by the dwarves. It`s best to sing it while walking with your mates to your trails, spades over the shoulder.
Props for Manowar haha Nah I like building with progressive metal esque stuff.. Cause it goes on forever, you dont notice the time go by =D Before you know it youll have built for 3 hours and have got alot of stuff done. Usually use Opeth or Agalloch.
I once got locked out my house with my ipod and a spade lol and so i started digging jumps to the Chili Peppers. Anything by them is good especially on a hot day.
