If that notice instead said that unauthorized reproduction, yada yada yada, was *not* prohibited, then and only then would it be legal, unless you have authorization to do so. Put simply, it is illegal to do anything with a recording that you are not authorized to do. Making a copy on MP3 (or making a copy in any other format) IS illegal. But that doesn't mean you'll get caught or even that the RIAA even cares to prosecute you for it.
