Yes a consistent frequency response across different songs is a challenge. You have two choices. Optimize the bass for each song or shoot for an average that sounds best for most and live with it.
Diana Krall's Temptation sounded OK acoustically) without any adjustments on my system. While playing Almost Blue the bass wasn't as prominent but still withing my limits of enjoyment.
What helped me was lowering the crossover frequency of my subs and moving them away from the wall.
