I know that there are four hidden music tracks (from the description of one of the videos here, and because I have a rip of the game's music which contains those tracks), but I can't find information on how to do it anywhere (I got a better time than BGNG in the video and it didn't work).

BGNG got them from hacking the ROM. As far as I know, there is no known way of accessing them in the game.
