My favorite room was a basement in my memphis home that was large enough for a hometheater setup on one end (complete with 7.1 sound) and a pool table on the other end. It became the best room in the house and could easily handle music and/or movies along with a pack of people playing pool. The room acoustics were pretty good as the room was 25 by 60 rectangle with concrete floors and concrete walls.
My current set up is a family room (had to leave memphis,ugh) so the setup is not as friendly I still have the 7.1 home theater and pool table but the room dynamics are not as good and the pool table is between the listening/seating area and the speakers. It is still the favorite room in the house and gets lots of use. I did have a dedicated room for music but found it did not get as much use since it was isolated.
