Back in the day, I had a employee who said I should listen to this album. Well I never thought that this person was playing with a full deck, but I thought that if it would shut him up I'd give it a listen. Well to this day I've been Captivaed bye the dark side of the moon. There are times I just can't get one or songs out of my head. Ony of the best albums ever. It's longevity proves it
