Not including albums that came out before the band had more hits, you will notice some Hits albums with obvious hit single omissions. Take 1977's The Greatest Of The Guess Who, which is missing No Sugar Tonight and Share The Land, two staples of their hit cannon. Or Bob Seger's Greatest Hits album from 1994, missing some huge hits like Shame On The Moon, Fire Lake and Shakedown, which was a #1 on billboard. And Billy Joel's Greatest Hits 1 & 2, a double album on cd and still it doesn't have Honesty or Don't Ask Me Why (depending on the cd version), either of which were big hits. And Don't Forget Pat Benetar's Best Shots, missing Sex As A Weapon and her cover of John Mellemcamp's I Need A Lover that would become an AOR hit. In each case they could have either found space on the album for inclusion (like on The Guess Who's Greatest) or omitted lesser known and/or newly recorded songs (live the live track on Best Shots or the new tracks on the Seger Greatest) to make space. Any other good examples?
