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.

He didn't write any of the song. He just made something that contributed to it.

Saying he wrote part of it is like the person who mixed Davinci's paint claiming to have painted part of the Mona Lisa.

It's more like if Mona Lisa incorporated a background from another artist.

Sets a pretty stupid precedent.

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?
