On the other hand, Metalllica can go swivel on a pointed lollypop stick. They're never getting another penny out of me.

Yeah, but while it's convenient (and fun!) to bash Metallica, I'm sure they are getting screwed in many of the same ways as smaller artiss are. They surely get more points than an act that's struggling to get by, but I'd be surprised if even mighty Metallica get more than $0.50 between them per album after all is said and done.
