Josh collaborates with tons of people, and has constantly taken backseat to other singers, even in his own band, much like having his frequent qotsa collaborator, mark lanegan, sing this song, and being iggy pops backing band, or being a drummer for eagle's of death metal, just like jack does for dead weather, and then jack takes his ego and collaborates with the guys in the raconteurs, so idk wether they can get along, but it wouldn't be because their egos won't allow someone else to have proprietary ownership of a song
