Phew, I'm glad I got all that yelling out.
Black Celebration is my favorite. It's dark, but it's got some really catchy stuff, too: Question of Lust, Question of Time, Here is the House, But Not Tonight, and the title track is amazing. Music for the Masses is good, too. Violator is probably their most accessible, and it's got Personal Jesus. Songs of Faith and Devotion is a classic as well. You can't go wrong with any of their albums, but those are the ones I would recommend first.
