I myself liked the fact that there was a mix between rock, soul, and R&B, rather than depending on just one (primarily rock) genre.
You misunderstand. I thought the style of music they was perfect. The individual song selection could have been better. Gaye is great. The thing is, whenever I hear a Marvin Gaye song in a movie, it's always "Ain't No Mountain High Enough." "I Want You Back" is basically in every movie ever made. "Escape" "Hooked on a Feeling" and "Spirit in the Sky" are also commonly used to set a 70s vibe. "Moonage Daydream" was really the only original selection--and
maybe "Cherrybomb."
My point was, for a film that was so precise and meticulous in all other aspects, it seems like the music director (Dunno if the songs were selected by Bates, Gunn or someone else.) just picked up a copy of
70s Soundtrack Mix that seems to be floating around Hollywood, put it in the player, and moved on.
