Ok so I rewatched Totoro for the first time since 2007. It was the last movie I watched before the release of In Rainbows, so it already has a Radiohead association... and this time I noticed a resemblance between one music cue (the end of the track labeled as Not Afraid in the US soundtrack release that’s currently on streaming services) with the piano part of Daydreaming, and also with Defeatist Anthem. I think both artists were copying from Joe Hisaishi. The plot of the mom in the hospital resonates with what was going on in Thom and his kids’ life at the time too, so they may have been intentionally referencing that music. Then again, Hisaishi is also quoting from plenty of pre-existing music in his soundtracks. Basically copyright is stupid and Radiohead would’ve been fine if they just stopped suing other artists.
