Thanks all for your reactions.

Just to get to the general topic: I don't want to sound ungrateful for the help being offered here, but I must say that I am aware of the copyright possibilities (worked for a record company, played in several bands with own songs, education is audio enginering, so I guess I am allready pretty well informed about all that copy protecting stuff). In fact the real question I asked has not been answered yet. A website that uses streaming audio (like some television or radio stations use). I don't know of any, but maybe one day any of you have come across such a site.

@Mac, thanks, still my intension is not 100% prevention, as I said I am aware of the fact that it is never 100% protected (copy-wise, I am not talking about like in law protected), but just make it not downloadable. Many people might use those kind of programs (and many others like it), but there are also many people who don't want to sit out that time and record realtime. For this last group I am asking this question.

@Toucher & Kemmrich: Thanks for the tip, I checked your site to see if it is download-proof. I am sorry to say, but I could just download the track.

@Don, thanks. I was as you can read in my post aware that nothing can be protected from realtime recording. I just don't want to make it all too easy for everybody. Many people will not record, they only use download options, which I would like to prevent.

@ Mike. Thanks for this too. I was aware of it since I protected my earlier songs through the tax centre, however only BUMA STEMRA means real protection. The tax centre only registers, which gives you a certain reliable proof, they don't help in any violations further on.
