"It isn't hard to understand why someone would want to label traditional music but it's impossible to comprehend why they'd marshall their musical preferences around it."

I've read this sentence several times, Glueman, but I don't really understand it. Does it mean that you don't particularly like traditional music so you can't understand why anyone else does? If that's the case, why are you here? Would you really like to replace it with something that you find more acceptable?
