Some bands change lineups, some change their musical styles, and some change...nothing, and you end up disliking them. Other, thought, change and you still love them even they don't even sound the same. Examples, for some of you that knows them;
Escape the Fate (original) > New singer (2nd album) > New sound (3rd album) = imo, they still sound good
Bring me the Horizon > New sound (2nd album) > New sound, again (3rd album) = I love all three of their sounds
Metallica (original sound) > New sound = Utter shit. I used to like them very much.
Avenged Sevenfold (old stuff) > Newer stuff = Crap. Remember their old sound? More punchy, overall better.
TL;DR - When a band changes, are you still loyal to that band because you used to like it, or you say "fuck it" and just listen to whatever you like?
