Just to name a few:
Deftones, Blindspott, Alice In Chains, Meshuggah, Staind, Jakob, ISIS, Katatonia, Tool, Machine Head (except Supercharger), Soulfly, Shai Hulud, Hatebreed, Pantera, Disturbed, Mudvayne (up until Lost And Found), Slayer, Digital Summer, Sevendust, Chimaira, Tesseract, Diana Krall, Robert Glasper, Miles Davis, Duke Ellington, Eminem (sometimes)...
Otherwise, I love electronic music (especially Drum and Bass, Lounge, Chill Out, IDM, and Ambient).,
