Havent been bothered by it, i rather have it boring and quiet instead of a orchestra theme playing while in a lobby and such. During games the only sound i wanna hear is "You killed an enemy" anyway
Its funny you say that because thats exactly what you get only the orchestral theme soul crushingly dull.
I play alot of Dungeon defenders and that game actually got nice music, but after playing for a year now all i can say is that whenever im on my sound in the headphones is almost turned off. After a while its horrible hearing the same tune over and over, im glad they did such a "boring" job with it because i actually wasnt thinking about the music until i saw this topic.
Its all opinions though so maybe you are right :) its just one of the things that im not really bothered with
