For one, no artist is shitty, someone will always find them to be good. For two, if it sounds good to you, and you like it, it's not shitty! This is more of a "what widely hated band do you guiltily love" or "what do you get ripped on for listening to" thread.
Anyway, that was sort of tangential!
I get crap from the metalheads for listening to stuff like Aphex Twin, Squarepusher, and 8bit peoples, crap from the indies for listening to extreme metal of any sort (black metal, death, grindcore), crap from the emos for listening to anything besides emo, crap from the ravers for listening to classical like Shostakovich or jazz like Ornette Coleman, and crap from everyone for listening to Bjork. The list goes on, it just depends on who I'm talking to and what bands I mention I like. Damn my eclectic taste in music.
