Okay, all that you need to do is either download discoinferno in midi form from the internet, make sure that the file name begins with "disco" into your songz folder. After that run Babyz and put on the disco record, your babyz will disco dance like there is no tomorrow. Now, you don't have to have the song disco inferno, you can simply add the word "disco" to the beginning of any of the songz in your songz folder and they will disco dance, but it is syncronized for disco inferno.
