To answer the why...
Since purchasing my M80's we've done a 180. We now listen to way more music than movie watching. I still watch movies (when the stars align) but in general if I'm home (and awake) the stereos on.
I've found alot of good online radio stations but I find I can't get the right bass. I know theres more for alot of the songs.
I'm pretty sure there has to be a way to get true full range at breakfast volume(65db @ 4meters).
