This actually gets discussed a lot around here. I think most will agree with me that the Qs8's do a great job for music listening. I have a number of music DVD's that I play in 5.1DD or DTS or 7.1 (PLIIx mode) and it sounds like your on stage with the band.
I also listen to CD's in 5 or 7 channel stereo mode on my Denon and they sound great also. I would say if you were only going to listen to cd's or other forms of music, you migh consider bookshelves or a second pair of mains. Since you watch a lot of movies, the Q's are a must in my opinion, there is nothing like them when it comes to surround experience.
