There would even be room for additional information if the artist has something to say. But for now, it's something that's really going to be used mostly within the industry in order to make a graceful and sane transition from the way music has been distributed for the past 75 or 100 years to the way I think it will be and should be in the future. It's really important that if recorded music is no longer going to be coupled to a physical disc and is going to be this thing floating in Cyberspace, that we be able to label it somehow.
Somebody puts something up on a web site.
Somebody comes and listens to it on RealAudio or Liquid Audio or whatever the technology will be in six months. The site is supposed to be paying a fee back to the performance rights organizations which then pay it back to the composer. They would listen to stations and log what was recorded and send in faxes of what station had played what record. You can't do that on the Internet. It's completely impractical and as things move more and more to the Internet, Musicode will be really important so that infobots can go out there and find out what's getting played, who's playing it and make the underlying economics of the thing work.
