The music seems to have strange disharmonies or reversed notes or somesuch. They happen in irregular intervals, about every second or so. Somehow I think the in-game music is not supposed to sound like this.

Notes for the linked file:

Audio starts after ca. 10 seconds with the music for the joke intro, which i then cancel by clicking. The problem I mean is with the other music, which is playing from second 18 forward (the menuscreen one).

I did click a fewbuttons to adjust the screen resolution, so don't be confused by the random beeps.

Sorry for the strange choice of format, but i was unable to create an mp3, and the wav was too big.
