Actually three:
1) People for whom any kind of darkness, pensiveness or melancholy is nearly ALWAYS a bad thing, to be avoided entirely. To them, "happy" means all light, no shadow;
2) People who have made friends (perhaps too good a friend) with darkness, pensiveness and melancholy. To them, "happy" means seeing darkness inside the light and light inside the darkness;
3) People who could give a shit about the topic. Perhaps that's you.

NOTE 1: Oh. In the spirit of full disclosure, you should know that the song "Gloria" was on the cafe sound system during the entire writing of this post.
NOTE 2: Why do Czechs, on average, seem to have such truly awful taste in music?
NOTE 3: But it isn't any worse, on average, than American's bad taste in music. In fact, it's the same music. No kidding. Bad American muzak abounds here.
NOTE 3: I think Laura Branigan was a #2 marketed by a bunch of #3's to a bunch of #1's. Just a gut feeling.
