Like any resource (page text, CSS, image) audio has to be downloaded to play. Once it's on the thief's PC, they can take it. The easiest solution is to only provide brief exerpts, not the whole thing; just enough to let them know what it sounds like (tell them how long it is, too). If you want to go through a lot of work, perhaps you could embed the music into a larger bit of audio, with your descriptive narration (or "incidental noises" of a real wedding), and format it as Flash or Shockwave or something. It would be more difficult, but not impossible, to extract the music, and it would require cleanup to be usable. Just as with displaying images, it's a tradeoff of how much work you want to put into protecting the audio versus the damage done by piracy. It will be impossible to completely protect the material, but you can do enough to discourage theft by all but the most determined cheapskate.

Nope. Even embedded music downloads to your computer, usually to a temp folder, and it still will exist on the client's machine. The only way to prevent someone from being able to play it is to offer a DRM protected file and well, I doubt anyone wants to deal with that.

I agree.  All I really want to do is put a list of suggest wedding music so that people can hear a bit of it.... so sounds like offering "bits" is the way to go.

Thanks for the help, folks.
