Mainmenu music Question.

[SilverSix311]

I know you can insert your own music into the mainmenu to play, i have done that plenty of times, but can you insert a whole song? Like insert it and fix all the reflexives and all that crap? I want to atleast put one whole song and if i could just keep the game from trying to load the other three that way i woyuldnt have to fix many reflexives.
