Would you prefer he demanded royalties instead, as their label would if he used a few seconds of their output in one of his films? Or that they just be able to use the sample without credit or royalty?
Roughly 40% of the lyrics are dialogue from two of his movies or describing scenes from those movies (Pulp Fiction and Reservoir Dogs), so a 40% cut of the songwriters' share of royalties is appropriate.
This song's lyrics solely samples audio from Indiana Jones - 100% of the royalties go to Disney? Morally, I don't think Disney have any right to it, but I could maybe tolerate some payment - however, proportionality?
