Problem. Audio buttons

I’ve created a DVD that is my professional reel. It plays the video portion perfectly. I also have a menu that has a number of buttons that I want to play songs when selected. I have found no way on DVD Studio Pro to create buttons that only play audio. For now the buttons actually are set to go to a new menu that will play audio as background. The only problem with this is that you can only have a total of 1GB in size for all menus on a DVD. How can I create buttons in DVD Studio Pro that only play music

Not sure about DVD Studio Pro, but in other tools, just use a simple JPG graphic file as “the movie”. That way it takes up little room but is played as if its a movie. A JPG picture with artist name and song title would look good, that way you know whats playing.
