I've tried to listen to the Misfits, but they just don't do anything for me. (For the record, I don't know if everyone loves the Misfits or if the Misfits are just good at marketing.) "Dig Up Her Bones" is probably the only acceptable song.
While I like what Crass was about, the music... Ah... I don't actively hate Crass, but I don't think I would ever have the thought, "I really feel like listening to Crass."
(On the other side of things, Propagandhi is my favourite and I'm wearing a Masked Intruder shirt as I type these very words!)
