Software for 30+hour long song?

There is software to do it, but none that I know that are incredibly easy unfortunately. For example you could use fl studios or any other D.A.W. (Digital audio workshop). You could also render it with programs you already may have. It might seem tedious but you could probably do it in windows movie maker, then export the file as an mp3. Or if you can't export as mp3. Then you could convert it with a converter. Hope that helps, but as for programs that do what you say really easily. I do not know of any :s
