Block MP3 Streaming For External Site

I have an MP3 flash shopping cart and need a small modification done to it. Its built in AS2 or AS3 with Flex I believe. I simply need an option to "NOT" allow songs to play depending on a query string in the embed code like "&allowplay=no". The point of this is, so I can disable the ability for people to play the songs depending on where I have the player. This is where I currently have the player [login to view URL] Its the large black MP3 shopping cart player. I want to not allow people to listen to the songs from soundclick, so it forces them to use the soundclick player instead. I dont want to totally disable streaming music as I still want to retain it at other locations. The cart must work 100% as it does now after your modication, just with the added ability to disable playing of music. I have the source files for this. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
