I want to download say 'Bad Romance' from Lady Gaga. When I download the mp4, there is no sound. There is a file audio mp4.

How does one fit the two files together??

Sorry, the file I downloaded does have sound. Others I have downloaded in the past had no sound, maybe I did something wrong.

Well its great you have done it finally.
But it would not be easy if you add video and audio file and there is no lip sync problem.
If both files have same time duration, there are lots ofGUI softwares like avidemux you could do this..

If you want to do this using command line you can use ffmpeg.
