Background music (beats)Difference is kendrick has objectively flawless musical composition, so they never gonna argue about beat selection, at this point most of his songs don't even have beats, they're composed.
It doesn't have to be hard hitting or repetitive for me, but I feel like he started out real nice and eventually like after tpab his vocal styles didn't really mesh well with what was going under them. I appreciate any artist that tries, but he just keeps trying harder and harder and it sounds worse and worse to me.
