Given the non specific nature of their credits I’ve always been fascinated by the notion of who came up with what.
Re Fables Driver 8 always seemed liked the quintessential Buck composition to me - jangly riff, Am and Em everywhere, ringing open chords. I have very few sources myself but as a life long fan you get a vibe; Buck = minor key jangly rock, Mills = country tinged power pop and piano ballads Berry = dark horse favourites. Then Stipe comes along and puts a beautiful cherry on it all.
Outside Fables this is what I know from interviews etc in regards to who came up with the basic song on which the others built:
Losing My Religion
This is all I’ve got but I’d love to know more. I guess most of the output was more collaborative but I believe the above were essentially a one guy deal re the music composition with Stipe then adding vocals
