Yes, you can have such a "redirection layer". But what you are trying
to answer here is a question without an answer: Anything that can be
listened to can and will be copied. Any approach you come up with
will be bypassable. It's the exact same problem that we currently
have with CDs and DVDs. Licensing your content under Creative Commons
can save you that headache.
