As a songwriter (of sorts), I would much rather my songs were out there in the world being sung or listened to by somebody somewhere - anywhere, (even for free!) than to have them condemned to eternal obsurity in some "collector's" cupboard.

What baffles me is, what kind of odd pleasure do collectors (aka hoarders) get from depriving the world of any kind of art form? Surely
after the collector's demise and through the passage of time, the items will cease to have any viable form of generating income or having any real value to the inheritors? They would be better sold off and/or made free to people who will cherish and respect their true value.   

(BTW, tin hat on ready for a possible 'Royaltists Revolt') ;-)
