Add-on Paid (mp3 player attachment)

#1
i was wondering if exist or someone could create a plug-in or Add to this forum , where a user uploads an attatchment like an MP3 song and play it but without being able to download it in the same post? and in sometime i deside to enable to download link it and could play it to?

Let me know if that exists or how much it would cost to make it
