The black & white newscast should use a different music file for the news intro - M_NEW1950 instead of M_NEW1970 (new1950.ogg vs new1970.ogg). Currently, only new1970.ogg is used. I'm not sure when the transition between the two is supposed to occur - I would guess 1964, because that's when the transition from the B&W to color animation occurs, but I don't remember it being that early (the name does say 1970, not 1964). It's also possible the B&W to color transition should be later. However, my memory of the game is over 15 years old, so that's not reliable.

I suspect the reason only M_NEW1970 is being used is that it's a longer audio file. Currently, the audio loops, which is distracting when the shorter 1950s clip restarts in the middle of the broadcast. I think what should be happening is: the audio plays as the into to the broadcast, the broadcast plays, and finally the music plays again as an outro after the newscast concludes.

Does anyone else have a better understanding of how the news music should work?
