I listen to a wide variety, but my favorite is liquid drum n' bass. This can be soulful and jazzy, then drifting more aggressive. Very Jekyll and Hyde range in sound: think angelic female vocals oven Amen breaks, accompanied with pianos and deep haunting/rolling bass notes.
I also like 90's hip hop (Tribe Called Quest, The Roots, De La Soul, etc) and jazz.
My 2 channel setup needs to play dual duty: background TV for a few hours per day, and then receiving my full attention for music and movies. I say "receiving full attention", instead of saying "critical listening", because I'm in it for the emotion and enjoyment, rather than seeking that last percentage of detail/shimmer.
