how do you get a song to play on a video you made?

If you have Windows XP, you can do that in Windows Movie Maker
Import your video into it, then drag all the clips it creates onto the timeline below.
Once you've done that, import your audio (it allows most audio formats) and drag it onto the timeline below your clips.
Then you go to Save to My Computer, give it a title, set a size, and save.

Sometimes it freezes, but it's nothing to worry about.
