Without going into much detail, I know of an indie studio where the game director wanted a lot of personal oversight on many things, music included. From giving other games' tunes as a moodboard to take inspiration from for specific tracks, to minutiae like removing an instrument, swapping an instrument for another one, slowing or increasing the beat...

I don't think it's a matter of indie vs AAA studios as a lot of people here are making it out to be. It's a matter of how big of a personality the game director is, and how much oversight they want over their game.
