itunes on .Mac with iWeb

I am trying to put a song on my .Mac site that I am creating with iWeb. I was able to put a small Quicktime movie and it plays on the site but not the song. In iWeb it does play. Is there some kind of licensing restriction in having that song play on the site? All of what I am doing is within the Apple software domain.

Thanks

Is it possible DRM songs won't play? I tried putting a song on just to try it out and it wouldn't play for me either. Then I picked a DRM-free track I bought via Amazon and it played fine.

Yes, I suspect that might be the issue, as a little movie clip that I have works. The thing is, I attached a song from iTunes to play in that video clip, and that does work. I did that in iMovie.
