The Andy Summer riff *IS* “Every Breath You Take.” In a just world, he shares songwriting credit. But this is a world run by lawyers instead, so go fish!
It was very boring until Summers put in his jazz chords.
The Police would have been just another band without the fabulous guitar work of Andy Summers. And I say this as a semi-pro singing bassist myself who’s covered a few Police songs.
Arranging and writing a song are two different things.
