I don't think theres anything wrong with labelling genres, its good for describing things. If I say "I love post hardcore, does anyone have more of that?" its a lot easier than going "hear me I out, I like punk sounds but maybe not necessarily punk songs?" What about movies? Can books have a genre? seems like a silly thing to take issue with. Alternative is a huge umbrella and it means something very different now than it did in the 90's when it meant pavement or sonic youth.
