I listen to everything

Seriously though, mostly rock and metal i guess, I do listen to a lot but them genres are the most important to me. I listen to quite a lot of stuff with unexpected instruments for their genres too, so for example Mr. Bungle who are a rock band but with a lot of Saxophone, or Secret Chiefs who are based in very middle-eastern music but also have heavy guitars at points. The system will only be in a bedroom, about 12'x12' roughly off the top of my head, just a standard carpeted room. And there will be no need to crank it really due to pretty thin walls in our house. So something sounding good at average listening volume, whatever that it :lol
