I was a charter member of Metallica's fan club waybackwhen, back when it was really quite cool for fans -- exclusive t-shirts, ticket purchase perks, exclusive merch, a fair number of meet'n'greets per city. Back then it was being run by their longtime personal assistant, Tony Smith, who was very cool to us even before the fan club was created.
Later, Tony was replaced, and the club went straight downhill. I let my membership lapse several years ago and never really looked back.
Metallica used to be extremely fan-friendly, even well into their sellout-arena years.
Later this practice declined.
So did Metallica.
I was also a member of the DTIFC back when it was cool, and have all of the Fan Club Christmas CDs (although after a time they became Fan Club Easter CDs, and I think they later petered out altogether). That one also I let lapse several years ago after DT kinda began sliding downhill.
