If you want some emotion (and not the sappy kind), check out "Boy Boy Boy" live:

It obviously carries some heavy emotional weight for Karl. I had wondered why it was included on the album, as a lot of people didn't like it, but after seeing it live, I can tell it has some heavy significance for them.
Of course, BBB's not your typical electronica song, but still.
