Led Zeppelin - Led Zeppelin
This is by far the most "no duh" inclusion on a list of records every man should own. Despite Robert Plant's flowing locks and skin-tight pants, there's something absolutely masculine about his voice. Add to his vocal prowess the undeniable power of Jimmy Page, John Paul Jones and John Bonham, and forget about finding a more amazing rock band. I don't think it's possible for any male to put this on and not play air guitar or drums, complete with contorted "rock-face." Which is why it's probably not the greatest record to play around your girlfriend.
