I suppose the idea was to have a very quick intro before the demo starts rolling, rather than an actual theme. It works okay when there is an actual demo, but since zDoom / GZDoom refuse to play old demos, it just loops on and on. And it's weird :P

Heh, even Wolf 3D had a longer and proper theme. As for Quake - it took soundtrack to a new level, making it a more ambient affair. But it seems it wasn't universally liked, as Quake 2 went back to having a more dynamic soundtrack, and Q3 continued this trend.
