Queen.

Greatest Hits, unfortunately, has but a very small sampling of Queen's songs. I have the Platinum edition, which has Greatest Hits I, II, and III, and much of their 70's songs are not featured.

My favorite Queen "era", if you will, was the 1970's. They had a "harder" sound, though still with the brilliant musicianship and solid harmonies. I highly recommend Queen, Queen II, Sheer Heart Attack, A Night At The Opera, and A Day At The Races.
Of their later albums, I love A Kind Of Magic , and the poignant brilliance of Innuendo.

News of the World, The Game, and the Works were pretty good too.
