I’m not a fan of Radiohead’s song. Like others have said, it’s too ambient and unstructured to be an effective theme song. It’s a good piece of music in it’s own right, but I think they made the right call.
That being said, I have issues with Sam Smith’s song as well. It’s a good song and definitely has the Bondian feel and melody to it, but lyrically it is all wrong. The lyrics suggest that the film has a strong romantic narrative, but I don’t get that at all watching SP. I tend to think of it in the same light as I do All Time High; that is, a perfectly lovely song that has nothing to do with the film it represents.
Speaking of Octopussy…Why on earth couldn’t Smith have used the word spectre in the lyrics anywhere?? After all, it’s not a difficult word to sing or rhyme like OP or Quantum. (Even Jack White was able to sneak the word “solace” into his song.)
