PSA: maybe he doesn't own the publishing of the song. the publishers are the ones who clear samples and interpolations. then of course he'd have no idea, but it would still be cleared and legal. since it is an interpolation, and Kavinsky owns the copyright of the master, the publishing company that owns the song (daft punks own publishing company) they have no obligation to even inform Kavinsky of the interpolation usage. i don't know if that's factual, i dug up all the info i could find about the rights and who owns what parts, but this makes most sense to me as i work with music publishing
