There's no way to say this without sounding like an old fuddy-duddy, but...
Good riddance! Any business that brings Social Distortion, and the uniquely anti-social fans they attract, to a family resort like Disneyland should probably move to a different neighborhood. In the early 2000's I went to the Sunday Gospel Brunch a few times and loved it. But too many times since 2010 I've walked past House of Blues on a weekend when they are hosting punk or hard rock bands like Social Distortion and it just brings the whole vibe of Downtown Disney to a kind of scary and intimidating place.
House of Blues made sense in 2001, especially when DCA opened and promptly fell flat on its face. But both parks are vastly more successful now than they were in 2001 and the entire purpose of Downtown Disney has changed. I won't be sad to see House of Blues go away and be replaced by a more civil and upscale restaurant or entertainment venue of some kind. With the brilliant moves TDA has been making in recent years, I have faith they will make the right decision for that building.
