Easy - buying the Lubinsky, because sooner or later SOMEBODY will come after his ass (or his estate's ass) and win SOMETHING. The more you fatten him up, the riper he is for the pickin'. CRuel and manipulative, yeah, but that's showbiz baybeeeeee.
Failing that, it's still buying the Lubinsky, because that demonstrates that the profitability on the part of the original label is not being devalued by the knockoffs, which means that said label is more likely to be swallowed up by somebody, which may or may not lead to Scott getting a belated but deserved (morally, not legally) piece of the pie through a variety of "collateral" methods.
Failing THAT - it's STILL buying the Lubinsky, because the image of an artist like Scott is not well served by countless LITTLE JIMMY SCOTT'S GREATEST ROMANTIC SLOWDANCEFLOOR CLASSICHITS compilation CDs on Butterpimple Records cluttering up every damn clearance bin in the know world for the low price of 25 cents, or some such. Having a product available on a "real" label, hower, is an opportunity for profile in the marketplace, so if Lubinksky were to pimp his Scott shit like he SHOULD have done in the first place, Scott might get no money, but he gets profile, which can be translated into $$$$ easier than not if you don't fuck yourself over by signing up w/another anusdrizzle like Lubinsky.
Fortunately, this is just a hypothetical scenario!
