Whatever the plans originally were for the movie's music, they were left on the cutting room floor in a brazen (and ultimately failed) attempt to recreate the "Guardians" magic.
Both

"Guardians" went with deep cuts and songs that you don't hear on the radio every day -- my local classic rock station doesn't play "Chains" all that often, but they love playing Queen.
Gunn understood that using the right songs -- ones that work within the movie's overall style and tone while not being too much of a "distraction" -- was more important than merely using songs. He knew that he could have used a bunch of oft-used 60s and 70s songs in the "Guardians" soundtracks and skated by on that. He chose a few popular songs, yes, but he still went for the deep cuts because they worked better. The "Suicide Squad" editors seemed to have chosen songs based on some ridiculous notion of "cool".
The "Guardians" films achieved success in part because Gunn cared about the synchronicity between the soundtrack and the film's other major elements. "Suicide Squad" achieved mediocrity partially because, in that same area, the editors gave no fucks.
