Our opinion differ on The Police, which were one of the top bands in the world for a short time between the late 1970s and early 1980s. The musicianship between the three of them was incredible. But they could not get along and so broke up after just five albums.
Sting was the primary songwriter in the band and the other two members seemed to resent it. But as much as Andy Summers is a great guitarist and Stewart Copeland is a great drummer, they could not begin to match Sting on writing lyrics and music.
Nonetheless, Sting typically let the other two write at least one song for each album and they were for the most part pretty awful.
Consider the non-Sting songs on their final album "Synchronicity":
Andy Summers (Police) - Mother
Stewart Copeland (Police) - Miss Gradenko
They should have just stuck to their instruments and let Sting write all the songs.
That is true, but Sting was the one the girls went crazy over, and that was what the other two resented most.
