YouTube user Smooth McGroove has recorded an a capella version of the fight theme from Mike Tyson's Punch Out!! and it is hard to believe it was made by a human being.
McGroove has dozens more classic video game themes on his YouTube channel, and they are all oddly soothing. Be sure to pop this on next time you try and take down Piston Honda or Soda Popinski. [Bob's Blitz]
