Ethan's right that the usual view is that music rooms should be livelier than HT rooms and I probably tend to agree with that view. There are standards for mixing audio for films and video and the whole audio mastering process for video is much more standardised than it is for music. The studios in which audio for video are mastered therefore tend to have much more uniform acoustic properties than studios for mixing music and you would need a "deadish" room in order to replicate what the mastering engineer heard in a video mastering facility.

Having said that, probably the big issue for me with HT surround sound is imaging accuracy. You want the noises to come from the right spot and you don't want a back of room to front flyby to sound like it's going from the rear of one side of the room to the front of the other.

With music, however, it can be a very different matter. Some people like precise imaging and soundstaging and others abhor them, saying you don't hear the music that way in a concert hall. If you like good imaging, you can get good results for both music and HT with the same room and acoustic treatment, but if you don't want imaging and you want a more concert hall sort of presentation for music, then you're chasing one goal for HT and a very different goal for music and you aren't going to be successful in getting both with the same room and acoustic treatment.

So the big thing is to be clear about what you want in terms of results for music and for HT. If it's the same, then no problems. If it's different, then you're faced with choosing one result over the other and putting up with the outcome that delivers for the times when you would prefer the other outcome, or running separate systems in different rooms, each optimised for that room's purpose.

What I'd recommend you read is Floyd Toole's book "Sound Reproduction" which is about acoustic treatment and listening rooms, especially multi-channel listening rooms though he has a fair amount to say about stereo along the way. He's definitely interested in accurate imaging, however, and his recommendations are not what I would suggest if you want to treat a room for music listening and achieve a result which downplays imaging.
