The bigger issue with your argument that IP, copyright, etc legislation needs to start having some separations. Medicine (physical) and mp3s (digital) are so drastically different that there's no way you can have one piece of effective legislation that covers both correctly.
Your example might not be making the point that you want. Drugs are covered under patent law while music is covered under copyright. Unless you're arguing that the MP3 process should not be patentable that same way as the process of making a new drug.
