well, I listen to everything except country. Love Tool. listen to linkin park, and other good sounding guitar music. But I do like to bump rap when i can, i just dont at the moment for lack of bump.
You could say i'm into more SQ than SPL. I have a pair of Audio Technique ATH-A700's (nice headphones) that i listen to music with daily on my computer and i think my system in my car sounds a tad better, could be the audio card i'm running off of on my computer but oh well.
i'd like to be able to give myself or passengers a headache if need me but still be able to enjoy good sounding music as well.
