I always liked weird electronic so dissonant sonics weren't a problem per se, but I didn't initially get emo/metalcore/post-hardcore (and 2010 screamo revival) but after getting first real job (and thus car) spent much time listening to baby sister's latest taste while in transit (dropping her at the train station near work, keep in mind that the stereo may have cost more than the car, and the boot was mostly filled with amp and sub).
Now bands like Amity Affliction, Asking Alexandria, Balance and Composure, Being as an Ocean, Bring Me The Horizon, La Dispute, Pianos Become the Teeth and Touché Amoré remain favourites. Fortunately they have generally developed artistically/creatively and remain interesting.
