Since the 80's didn't put an end to Antrax and their ilk, might I suggest a little ciprofloxacin, doxycycline or penicillin ....
What Scott Ian needs to realize is that people have only so much time and money for entertainment. Percentage spent on entertainment, based on take home pay, has remained pretty much static for the past 20 years. The time people have is now distributed between, online video (youtube), gaming, blogging, websurfing, reading news, facebook apps (farmville, mafia wars, ick ..etc), texting, talking on their cell phones, tweeting, chatting, skyping, and much more.
The other set of problems the music industry faces are, mp3 music singles have replace album sales, there is no need to repurchase music in newer formats, the loss of "media failure" resales (scratches, unwinds, etc), artists giving their music away online as advertising for scarce goods, and 4 million other artists competing for the same eyes and ears.
What Scott Ian is now facing is a failure of the monopoly status of the record labels due to competition, and efficiencies creeping into the system. It will only get worse as time goes by and new business models are developed. Business models that the record labels cannot use, as they need to be geared to the individual artist.
So my suggestions are learn about facebook, twitter, and Google+ or hire someone that knows how to use them. Learn how to post your albums on Amazon, iTunes. And most of all connect with your fans. See what they like, take advice on the way the next album should go, allow them to participate in it creation. Hold a best lyrics contest, best rift contest, best remix contest.
