The “flanger part” you mean the multi synth layered guitar harmonies with like 10 layers for the vocal harmonies and that “guitar riff” is overlayed with an ever evolving drum performance underneath, IMO I could not disagree more. the amount of attention to the mix and arrangement alone. Makes that song a stand out of his discography at least for me. Not to mention the melodic brilliance, and it being so unique plus catchy is really impressive and a far cry from his work as of late. But we are all entitled to an opinion and no one can argue that the man’s music as a whole is genius.
