An interesting fact is that the human ear perceives "Loud" by when distortion occurs. In other words, a system overloading at 85dB will sound louder than clean sound at 95dB. (Don't quote me on the exact numbers).
Some music needs to be felt as well as heard. In my case this is organ and sometimes massed choral, but I recon that pop would also apply. My system includes, in the front, three 12" and three 15" drivers working in conjunction with three MG1.6, with six 600 wpc amps powering the whole mess. The surround channels are only four 7" drivers and 450 wpc. With the right recording, I can just begin to feel a real pipe organ at work. If you doubt this, consider for one moment the "drivers" that the organ uses!
Sometimes I realize that I am playing the music too loud. The way I notice this is by focusing on a soloist, for example a violin or vocalist. I know how loud a single violin can play, and if the reproduced violin is louder than that I turn the volume down. Unfortunately this depends on how the recording has been mixed. Many times the soloist is boosted relative to the orchestra, so that if the soloist is right the total sound is too quiet. (One advantage of multichannel is that, if the mix puts the soloist in the center channel, which is usual practice, you can rebalance a recording with overemphasis on the soloist by turning down the center channel).
Finally, I do have tools to measure SPL. IMHO, over 95dB, neglecting brief peaks, is too loud.
