when i was a postie in Orpington back in the late 80's/early 90's i used to have a selection of Queen songs on my walkman to help me get around the 'walk' quicker.it does make a difference,i used to get done about 20 minutes quicker with the walkman playing the songs than without it.
the best ones to walk quicker to were from 'the game' or 'hot space' ,notably 'coming soon' and 'staying power'
