I don't know about listening and wearing, but I have so many wfmu t-shirts now (like 4 or 5) that it's inevitable. I will say that I wore the "Eat Flaming Death" shirt while buying beer at the Korean liquor store by my place and the lady at the counter seemed transfixed and intrigued by it. I was kind of afraid it might be offensive in some way or something, with the whole faux-Mao thing, but she said "I like your shirt", so that's cool.
